Hello. Recently I have changed education organisations and therefore I have a new Adobe Login. My old one was deactivated before I could properly sign back out of it. So now, when I open Creative Cloud, it gives me the image that you can see attached below. If I click 'Sign In' this Sign Out box just reappears, as an infinite loop. Any one able to help? I am just looking to sign into Creative Cloud with my new login, but that does not appear to be an option. I have tried completely uninstalling Creative Cloud, as well as all of my Adobe products, but upon reinstalling I am met with this box again. The 'Sign Out' option in the Help drop down is also greyed out.
What may work is to remove everything and do a fresh install
This was the solution, thank you!
That is the one that did it! Thank you for your help!
I'm having the same issue as OP. However, in my case the cleaner tood did not work.
