Which operating system?
Can you post a screenshot showing the issue?
I just found out the issue is bigger than i initially suspected.
When i go to my profile, in the section Plans & Products doesn't show my plan, its just empty like i have no plan.
But i'm paying my subscription regularly... probably no one in the forums can help me and i will have to wait to call adobe tomorrow...
I've been having issues with this validation loop for almost a month.
Today i had to work from home, so i had to solve this for good.
But i had to fully uninstall, use adobe cleaner tool, and followed every instruction to solve this issue. Took more than 4 hours to understand that my account had no plan, but as i said i'm supposed to have Photoshop + Lightroom subscription, which was freakin weird.
So i noticed: apparently when i looged in with firstname.lastname@example.org i had no plan, but with
VINICIUSCABRAL112@myemail.com everything is fixed.
