No problem, J_F_S, it is a challenging time for all of us right now. As things are reopening, I try to remind myself to act like the customer I would want to interact with, but it can be tough.
If you are not encountering a network error, then please complete the six solutions listed in https://helpx.adobe.com/creative-cloud/kb/creative-cloud-application-recognizing-available.html. Your original post indicated that you already applied these steps, but solution three through 5 may have been unsuccessful if not implemented as directed. For step five, people will often skip it, or rename the incorrect OOBE folder. This can lead to solution six being unsuccessful. If you have any questions on any of the six steps, then please update this public forum discussion.
Hi,
I had to deinstall all aplications and reinstall.
This was a real mess of work. I hope that will fix it for the next updates.
Cheers
