I started my After Effects CC 2017 7 day trial today due to issues with my older version. I was able to open it up and create an entire video using it, once it exported I exited out and my creative cloud still said "7 days" was left in my trial. I opened it up to begin another video and my trial has expired????? This is very frustrating
Nobody can tell you anything without exact system info or other technical details, but chances are that whatever messed up your older version also afflicted the CC trial, so you realyl have to solve the deeper underlying issue, not trying to evade it.
Did you ever resolve this issue, Grant C? Let us know.
