Since when ?
changed title to actual problem - ele
I am able to log into the game with no problems... so again this is an after event problem...
1) Be sure to have tried logging in first to battle ground server... then exit... then log into regular servers.
if that does not work:
2) Try to log in after the event time is over
3) try to log in after daily reset (Midnight EST)
4) in the past if you get stuck after this point they often just make you wait until Tuesday maintenance.... but try writing the support email and getting a ticket number and if in 48 hours you can still not get in game, post the ticket number in a thread for FOK.
You will have to contact support because the problem is only affecting a few people and is not game wide.
(yes it is a game bug of sorts but not everyone gets affected).
