What is the exact error your are receiving? ("Unable to decrypt password" is not an error message). What browser are you using?
Using Chrome. The error appears randomly when I get kicked out - sometimes no error at all. I will try to recreate but recently I just get kicked out with no error at all.
edit: I keep trying but the error is not showing up anymore - just getting kicked out.
edit 2: If it will help, I can get a video of my screen during the login process and PM you.
edit 3: I forgot to mention that I have a Google Drive backup. Can I use this to help me out in some way?
