Activation Required for CS5.5 Master Suite

[shannonc84]

I purchased, installed and registered Adobe CS5.5 Master Suite two weeks ago. Since that time I keep facing prompts to activate the suite, which I was under the impression should happen automatically..?
An alert reading 'Unable to activate CS5.5 Master Collection' is followed by 3 options:

- Retry activation

- Contact customer support

- Remind me later

I have tried and tried again to retry the activation. Each time, no matter where I am or what internet server I am using, I am constantly met with 'Please connect to the internet, then press Continue'.

Today I tried contacting Customer Support. After being on hold for 45 MINUTES (!!) without once speaking to a human being, I gave up rather disgruntled.

I have pressed remind me later day after day - but now my days are limited.

What should I do? Any help would be greatly appreciated as it seems that once the product is purchased and money is in their hands, Adobe are impossible to contact. Definitely not the service I was expecting.

We need to know more about your setup - operating system, hardware specs, how are you connected to the Internet. Could be anything from insufficient privileges so the activation never sticks to your network setup simply never getting connection to Adobe's activation servers...

Hi Mylenium,

The suite is installed on my MacBook Pro (Mac OS X Version 10.7). I'm not great with computers language so am not entirely sure how to provide that information - but I'll give it a go!

My laptop has a 2.2 GHz Intel Core i7 Processor, with 4GB 1333 MHz DDR3 memory. The startup disk is Macintosh HD.

At home I am connected to the internet via wireless broadband.

At university I am connected through the uni wireless network.

At work I am connected via a network cable.

None of these locations proved effective!

Last night I tried removing the Adobe suite from my computer and then reinstalling - however, this didn't help at all either.

I'm at wit's end!

Mac OS

1. Open a Finder window. Choose Go > Go To Folder.
2. Type "/etc" (make sure that you're is logged in as an administrator).
3. Select the hosts file and open it.
4. Look for any entries that refer to activate.adobe.com and delete them. For example, 127.0.0.1 activate.adobe.com and delete it.
5. Save the file and close it.

Thanks Manish, it appears to have worked. Life saver!

Change your system clock to Pacific Standard Time and then check.

I'm located in Melbourne, Australia. I tried changing my system clock to Pacific Daylight Time but that didn't help.
