Hello A long time since I logged in, so long that I forgot my account name. But the PA Launcher would not accept my keyboard input of the @ character, which happens by me pressing the "Alt Gr" and the number 2 key. Don't know if this issue exists with other types of keyboards.
Do you log on with email or is it part of your password? I have never tried it with a similar keyboard but most likely @ doesn't work on US keyboards too . Will do later. I'm sure you are copy/pasting it right now but it's also possible to change your password.
