Try running as admin and see if it says you've been banned.
I cannot log in to my account either. Same issues. I also get error code 1.2. Researching this I found a post from 2014 about a corrupted launch file. But I can log in to my husbands account on the same computer just fine. Running as admin revealed "this account has been banned". So I will be writing a ticket.
Edit: the issue was resolved
