Invalid Credentials bug

Dear MPGH forum,

I've recently encountered a bug, it doesn't allow me to log in anymore, not even with valid passwords/usernames, it keeps saying "Invalid Credentials". I'm sure many of you had this problem too if you log in with a lot of accounts.

Does anyone know a fix for this?

Many thanks,

yeah, i don't know why this happining, but i think when you log in to an alt account that you don't own basically it blocks your pc, you either log on VPN or you just restart your computer.
