Same issue here. Got fed up trying to get past Pipin and went to do 50 RDM quest. Got disconnected. Tried to get back in, got 90k errors for half an hour, went to take a nap. Came back, loaded in went to do RDM quest again out of hopefulness, disconnected again. Constant 90k errors despite waiting patiently in logon queue (not trying to cancel and force my way in).
