confirm that your account shows the subscription(s) you expect (and that the adobe id used in the next step is the correct one) by logging in here and checking your subscription status, https://www.adobe.com/account.html
then, if it is current, sign out and then back in to your cc desktop application using the same adobe id used with the above link: http://helpx.adobe.com/creative-cloud/kb/sign-in-out-creative-cloud-desktop-app.html
Hi, the for your support. Of course I've already Checked my account and my subscription: they're both active. I signed in/ signed out different times, but I still have the problem.
Seems that a Kind Of a "forced" sign out happens each time I close Photoshop...
in that case, the following is from adobe staff:
Please ensure you have the latest version of the Creative Cloud app installed
We also have this solution for the having to sign in on every product launch
If you're continuing to have issues please post back
