Can't Activate/Validate My Copy of Creative Suite 6 (Legitimate Copy)

I can't activate my copy of Creative Suite 6, Design & Web Edition). I seem to be having 2 problems.

I know it's a legitimate copy, not counterfeit. I bought it at the University bookstore when I was in grad school, not through Amazon or a 3rd party online. It's registered to my account & has been since I bought it. I've never shared the serial number. My old laptop died & I'm now trying to install it on my new laptop. I'm on a Win 11 machine & I know the programs run fine because my previous laptop was also running Win 11. It won't validate, apparently for 2 different reasons.

Problem the first - Creative Suite can't connect to the internet. I have no idea why. So, I attempted to do the offline validation. Where I ran into problem #2.

Problem the second - When I put in the request code & the serial number, I get an error message saying that I have CS6 activated on more than 2 computers & it won't give me a response code. I managed to deactivated it on my old laptop during a brief sign of life. I don't have any other computers I'm using. I haven't always deactivated it on previous laptops, partially because I didn't know I needed to but mostly because I couldn't. I tend to use a laptop until it dies, although in one case, the laptop was stolen. When I look at my account to see what machines are activated, it says I don't have any. 

So, according to Adobe, I have zero copies of CS6 activated but somehow also have more than 2. The online chat is no help. It just tells me there's no support for CS6 anymore. Which, I don't need support for the programs -- they run just fine. I need support for Adobe's verification system. I'm assuming what I need is some kind of reset on the activated copies but I have no idea how I would do that. 

Thanks!
