Hmm i havent heard about it before.
But remember to make sure you put the RIGHT username.
I have also tryed to enter, and i couldent see any of my Characters. BUT it was becouse i dident type my username correct.
lets say my username is DakillerMu.
If i type dakillerMu instead of DakillerMu, i can enter, but i cant see my characters.
So you have to make sure, that you type your username 100% correct.
Hope this can help.
