Login server problems
By the looks of it the login server of EQ2 seems to have problems atm.
I'm not sure if it's for every server but it's "hard" atm to login into splitpaw. Sadly i could find any note about it.

Due the Update of the launcher you will have to login again (Accountname and password), but also you have you have to check your Server! i play on Splitpaw and when i tryed to login i got the message "server Splitpaw not found" because i was still set to "us English" after the launcher update.
