Creative Cloud is telling me my Photoshop trial has expired, though I've been paying for it for over a year

Whenever I try to open up Photoshop from Creative Cloud, it gives me the "Buy Now" button instead of a button to open it, and when I do manage to get to it from my files, it pops open a different window that says "validating software license..." that will shut down two seconds later, then pop up again. It won't stop going through this cycle of shutting down and popping up. When I go into my account, it shows that I do have Photoshop. I've tried everything from uninstalling Photoshop and reinstalling it, logging out of my account, and restarting my computer. The only thing I haven't tried is uninstalling Creative Cloud because whenever I try to do that it tells me that the application is needed for other apps to run and it won't let me, even though Photoshop is the only app that I should have. What do I do?
