stupid error that won't let me log in

[Eangarra]

I attached a jpeg of the error. maybe someone can help. First I cannot log on because my wife is playing on our other computer, now I use my phone as my tether to try to get on and it crashes.. There must be something I need to change..had no trouble last night as I played for hours just myself and a friend(not on the same IP obviously) The only thing I can say is last night my character stopped moving towards the end of my play time, logged and came back and it was fixed but now I try to log on and it crashes with the attached error.
