Can't no longer run CS5 after Windows crashes on 2 PCs

This concerns Adobe CS5. Recently, Windows 10 had catostrophic crashes on both my desktop and notebook PCs; after which neither was operable to be able run my Adobe software and Deactivate my licenses on each machine. Up until the crashes, my CS5 software has always worked fine on both machines. I upgraded to Windows 11 on the desktop, and reinstalled Windows 10 on the notebook. After reinstalling CS5 on both machines, CS5 won’t work on either, telling me “Activation limit reached...”

I called Adobe Support, but they refuse to reset the Activations, and I’m unable to do so when logged-in to my Adobe account. Adobe Support and their website states that “Activation servers for end-of-life software have been disabled.” But this is contradictory to the facts! If the servers are disabled, then why was I able to run CS5 on both computer under Windows 10 for all these years, including until recently? Something stinks. I’m a very light user of Photoshop, InDesign, etc., and I don’t want to have purchase an annual subscription.

PLEASE LET ME KNOW IF THERE’S A WAY I CAN GET CS5 RUNNING AGAIN ON BOTH MACHINES. THANK YOU.
