l'm afraid we can't help you with subscription issues on a public forum. You'll have to contact Adobe during normal business hours (US hours). We're now in the middle of the July 4th weekend in the US, so you'll probably have to wait until Monday:
Can you try the following:
- Launch the Creative Cloud Desktop application
- Click the Gear Icon on the top right
- Choose Preferences
- Click Sign-Out
- Then click the Gear icon again and choose Quit
- Restart your computer.
- Launch the Creative Cloud Desktop applicaiton again, and sign-in with the Adobe ID and password associated with your Adobe InDesign CC membership.
Fingers crossed that will work for you.
If that doesn't work review the following Adobe post: https://helpx.adobe.com/manage-account-membership/cc-reverts-to-trial.html
See if any of the resolutions (and steps) in this post will fix the issue.
If none of them help, let us know and also try to provide some additional information if possible (so that it might become clearer to one of the many helpers on this community forum what the issue is and how to help you fix it), for example what operating system are you using? (Mac / Windows), and what version of the operating system (e.g. Mac OSX 10.10 or Windows 8.1) etc.
Hope one of these will manage to get you up and running again with InDesign.
Let us know how you go.
