Please click on "license this software" when the trial box appears.
Enter your Adobe id and password to activate and then try to close and re-launch.
Please reply if the issue persists.
Thanks, but the issue persists. I already do what you have described every time it happens (see my original post "I have to repeat the sign in to cancel the window. ") and the problem continues. If I quit right after signing in and relaunch, then no problem. When I launch after restarting my computer, then the process starts all over again. Since my original post, I have launched both InDesign and Illustrator and had the issue with both.
Please rename or delete SLcache and SLstore folders.
For Windows: C:\ProgramData\Adobe For Slstore
C:\Program Files (x86)\Common Files\Adobe For SLcache
For Mac: Open the finder window click on go and choose computer and navigate to
and delete the SL store and SL cache folders.
Then try to re-launch and reactivate your product.
That seems to have done the trick. Thank you very much.
