PS Elements licences deactivating computers

Hello everyone 

I own a few licences of PS Elements 2018, 2019, 2020

I activated these licences on many computers along time, but those computers are gone now and I can't access them 

In the past, I could see in my account in the "activated devices" menu a list of all computers using the licence and I could dissconect them  

Now, it is empty and I cannot deactivate them nor access those computers 

I got a now computer in which, obviously, I cannot activate my PS Elelements 2018 anymore 

How do I go around this? Is there any solution? 

Support is telling me that my software is too old and there is no support 😞 nor they can access information about these licences (oh....Adobe, very nice 😞  

thank you
