did you sign in through mycreativecloud.com? You also may need to sigh in at each app the first time you use them
As J Potter mentioned you will have to Sign Out and then Sign In to the Apps.
The steps you need to follow are:
1. Launch the application which says you are in trial mode.
2. On the Creative Cloud application trial screen, click on "License this Software".
3. Sign in with your Adobe ID associated with your Creative Cloud membership.
