I CAN'T USE PS5 THAT I BOUGHT BECAUSE YOUR SYSTEM SAYS IT'S ATIVATED TOO MANY TIMES!

I own PS 4 & PS 5 - 

I can’t get PS 4 to work photomerge so I tired PS5 

Well the swell guys at adobe, say I can’t use PS5 (THAT I BOUGHT AT FULL RETAIL) because it’s been activated too many times and that I have to go on the old PC and de-acitivate it...Well guess what? I CAN’T THE PC’S ARE LONG GONE!!! NO WAY TO TURN ON A MACHINE THAT’S EITHER BEEN PARTED OUT OUT THROWN AWAY!!!!!! 

I HATE HAVING ACCOUNTS!! I HAD TO CREATE THIS ONE TO ASK THIS STUPID QUESTION!!!
I AM NOT ON SOCIAL MEDIA AND HAVE NO INTEREST IN ANYTHING ADOBE HAS NEW!! I AM NOT PAYING FOR A SUBSCRIPTION TO USE SOMETHING I CAN GET BY WITH AN OLDER VERSION THAT I PAID FOR!!!!

How do I get around this to use the software I paid for!?!?!?!?!
 

Thanks 

ARRGHHH I AM SO FRUSTRATED!!!!!
