CS5 Design Premium activation limit reached after successful deactivation of old computer

Hello,

I own a licensed copy of Adobe Creative Suite 5 Design Premium. I successfully deactivated the software on my old computer using Help → Deactivate. On my new Windows 11 computer, activation still reports "Activation limit reached" and says the serial number is activated on two computers. Adobe Customer Care referred me to this forum. I have the original serial number but my original Adobe account was associated with an email address that no longer exists. Can an Adobe employee or community expert advise how to obtain an activation-count reset for this legacy product?

After deactivating CS5 on the old computer, I did not remove it. Clicking on Photoshop, a box came up with a long license agreement.  I accepted that and the next box asked for the serial number and then a choice of a 30 day trial or “Buy Now” - for CS5.  Seemed dated and irrelevant since I expect to decommission the old computer anyway.

Not trying to steal from Adobe.  I bought a perpetual liscense product and would like to continue to use the programs. 

Thank you.

Doug
