Here's how Adobe works. Blocked serial number Adobe Creative Suite CS6

editb31393992 sorry for you. I had exactly the same problem as you. Adobe confirmed that my license was ok when I bought the software and they blocked my serial number recently. Despite the proof of purchase and the email they sent me to confirm that everything was ok, they didn't want to resolve the issue and tried to sell me their subscription.
They act like mafia and I don't think you'll find any help for your problem here. May be i'm wrong but it seems like they're all trying to justify their employer's behavior as perfectly normal. Some of them are even trying to get us to accept that a perpetual license is a license for 3 to 5 years maximum... it's just pathetic...

The chat person sent me an email and I replied to it.

Hi Edyta,

I see that you first posted about this issue on 25 Jun 2018 and Adobe Employee @DebbieW1964 from the Adobe Genuine Team sent you a PM. What was the result then?

It certainly won't bring any fans to Adobe. That's why I personally use and encourage an alternative - affinity from serif
I paid 1000E in 2015 for CS6 which I can't use.
As of today, Affinity is almost 5x cheaper.
And if you look carefully, Adobe CS6 can still be purchased for less than EUR 500 and Adobe has no problem with such sellers, it just picks on the end customer.

I have the same thing, after 8 years. Cs6 Works fine with a new system, on a new computer. If you don't need fancy new features, just basic photo or illustration editing, you don't need to buy a subscription for this. Comments like - find a better job so you can afford CC should be deleted.
I paid for the program I use and it is sufficient for me, and I use it occasionally - 1-3 times a month, not commercially, I do not make money from it. I used... Because Adobe canceled my subscription and encourages me to buy a CC subscription.

try to not get upset by anything any of us post.  none of our opinions have any impact on adobe, though it's pretty understandable why being told to do things you've already done would be aggregating.

After five years, however, Adobe blocked my number. After talking to them and handing over the proof of purchase and transcript, they admitted that they would give me a new number. Now, again after five years, the number they gave me was blocked.

 

You're unprofessional

Do you understand that you are talking to volunteers on a public forum who cannot access your records? Volunteers also cannot override anything Adobe tells you.

We don't have any way to know if you have a legal copy or if you accidentally purchased a pirated copy. We cannot see your records.

You have been told several times to contact Adobe Customer Care and told how. You have to do this since you still have questions. This time, get a case number at the start of the call and ask for Tier 2 support.

After talking to them and handing over the proof of purchase and transcript, they admitted that they would give me a new number. Now, again after five years, the number they gave me was blocked. They say that the number they gave me cannot be used in Europe.

Is "they" Adobe or someone else?

Serial numbers are linked to the installer you have, several installer can not be acquired in Europe/Asia/Americas. They are also linked to the type of software: educational or retail, standalone product or suite. So the correct installer with the correct seial number is needed. 

If a serial number hits the black market, it gets invalidated.

Now they dismiss me and don't respond to my emails. And it's not true that Adobe doesn't communicate via e-mails (someone wrote that somewhere on the forum). The chat person sent me an email and I replied to it. I also know that Adobe employees read the forum.

By @editb31393992

You are confounding initiating a communication and follow-ups. Whatever e-mail you have, can only be used when you are told to use that mail address, If the mail address is that from 5 years ago, it may be no more valid.  There is no support e-mail and the only official ways to communicate with Adobe support are chat and Twitter. There are people reporting also some Facebook channels, but they are not officialy published, so we can't tell you to use them, as we do not know if they work as expected.

Adobe employees read the fora, but it is not guaranteed that your precise message gets read or when they notice it, if they pick it up. Reading the fora is done in their "free" time, with a few exceptions.

In this way, they are trying to force me into a cloud that I don't need. The CS6 package is enough for me. The company I work for also uses this package, so it wouldn't be beneficial for me to switch to the cloud anyway.

Professionals should abandon old software and upgrade. The productivity gain is worth the fees. I bet, the computers are of a newer generation, the OS has been upgraded, and other productivity tools too. If they are still working with CS6, then they are not professionals in this field. 

You're unprofessional, because the CS6 package was supposed to be for life, and you're slowly blocking everyone's numbers. Could I easily register a serial number that was fake (as Adobe claims) with Adobe? The answer is no, because such numbers could not be registered.

By @editb31393992

We are fellow users of the software and most of us are professionals. Some of us still have CS6 lying around somewhere (I have CS5 lying around somewhere), but we do not use those software anymore, as we would not, or only with hurdles, be able to exchange data with other users. Those using Macs can not use the software anymore, because Apple does not run old software on new machines.

Now to your problems with getting twice your serial numbers revoked: I do not know, how this can happen, when you buy at official channels. And I do not know, how an officially, by Adobe issued serial number, should not be valid in Europe. Nobody here can comment on that, and nobody here can help you with that. We even can't be sure that the serial number has been revoked or that the software stopped working, because you installed some software incompatible with the older CS6.

Anyhow, this forum cannot be of help, as we can't solution your problem. It may be that a friendly Adobe employee jumps in, and can help, but the only official way to contact Adobe support is the way as published on Adobe's support site. You may try out other roads, like Facebook, but there is no guarantee that this works out for you.

"Life of the software" does not mean "forever software."  Sorry.  Every software reaches it's end of life eventually.   And Creative Suite is no exception. Most modern devices can't support 10+ year old software anymore. 

Did the seller submit a transfer of license request to Adobe prior to the purchase?  If not, you don't own anything.

email is not a valid way to initiate adobe contact.  there are 2 ways to contact adobe; chat and twitter (now x):

chat:
use a browser that allows popups and cookies, and click here, https://helpx.adobe.com/contact.html?rghtup=autoOpen
in the chat field (lower right), type AGENT
be patient, it can take quite a while to reach a human.

twitter/x:
tweet @AdobeCare

p.s. if you're contacted by anyone (via email or private message), it's much more likely to be a scammer than an adobe representative.
