Would you believe....a PS5 issue in 2026?

First, I'm reasonably confident I'm in the wrong place, but I can't seem to contact Adobe directly, so...help?

I first purchased my copy of Photoshop 5 in 1998. When they moved to the subscription model, I decided not to follow, but PS 5 was all I ever needed, to this day. My most recent computer had a MB malfunction (now replaced) and now tells me I have it installed on more than 2 computers so I can no longer use it (in 2 days).

If this is the end, then so be it. I can't deactivate it on a computer that won't boot, and it was also installed on a laptop that I forgot I had to deactivate it on, that I switched to Linux, so that won't happen either. Can anyone give me a way to contact Adobe directly or help in any way? Even pointing me towards the right forum would be good.  Thanks all!
