Always Asking To Sign In

I've installed the 'apps', to do so I have to sign in via the Creative Cloud 'app'. Next time I try to open anything I'm forced to sign in and get a stupid verification email. I've completely uninstalled, used the Adobe cleaning tool. Re-install and it makes no difference, I'm asked to sign in for every 'app' I try to open!

There's nothing helpful on the Adobe site and it's impossible to contact anyone.

I'm asking here in the hope someone may have a clue because Adobe don't care, they take your money and provide no support at all.

I'm using Windows by the way.
