You really need to contact Adobe Customer Support for activation issues.
Some people - and I'm not saying this has necessarily happened to you - have been bitten by scams where they bought counterfeit software and originally got bogus serial numbers which worked at the time, but have since been blacklisted by Adobe. I sincerely hope this is not what happened to you.
Good luck with Adobe Customer Support. I've always found them helpful with regard to activation issues.
yes, you need to contact Adobe Customer Support for activation issues.
Thanks heaps. I have contacted adobe and sat on the phone for hours only to be told they can't help me and directed me to the support chat, where I was then told they can't help me I needed to do this.
Ahhh. But thanks heaps anyway.
