Same. Got the Error 90000 while zoning from inside the Waking Sands to the outer lobby of the Waking Sands and now when I try to log back in, I get the 3102 error.

I might as well stop trying to play the game. I've been through a few betas for games, been through early release launches, and this honestly has to be one of the worst. I got more game time during Aion's, SWTOR's, and some other MMO's first few days than this one.
