I get the White screen and login, then the grey screen appears after that. Once the grey screen is there, nothing else happens. I tried just closing it, but then Launchbox is unable to find any games.
I tried just using my PSN email & password, but I get an invalid user/password error. I still am unable to try and disconnect my PSN account, as I won't be able to log in at all at that point. Maybe if I connect a different system, it might work better?
