Creative cloud needed to resolve this problem, AE error 106 etc

Hi,

Yesterday, my AE sent the message "We can't verify your subscription status". I clicked "Try again", it seemed to work, but after 10 seconds, the application crashed with error code 106.

Following the instructions on the forum, I logged out from Creative Cloud, closed the app and tried to log in back. Then I got the message "ACC is needed to resolve this problem". I chose the "Repair" option: I see CC is downloading, but once the repair is done, same problem again: loading CC takes too long, CC needed to resolve this problem etc.

I checked the error on the forum, seems to be quite frequent. As advised on some topics, I uninstalled everything, removed the various OOBE and application manager directories, re-installed. I can connect back to CC, but then the same problem happens again: first AE unable to verify my subscription status, then CC not being able to load. 

I am using Windows 10, my OS is up-to-date, and my network settings seem to be fine.

I'm completely lost now and I have a project to deliver by Friday, so anyone having a suggestion is welcome!
