so i had this problem, the creative cloud told me i had updates , so i updated Photoshop cc
then i tried to start it, but it told me i didn't have any subscription so i can only use the trial version.
The point is i already have that annual subscription for both lightroom and photoshop , and there's no problem with lightroom.
I tried to delete and re-install it, nothing happened
i'm using a mac if it helps .
