I have the same exact problem. I just recently reinstalled the game to see if that would fix the problem and it didn't do anything. I noticed that when I installed the update that the update server crashed and I had to reconnect same exact thing happened the first time around not sure if that's related or if I'm just grasping straws.

I also just tried to emulate the same situation on my friends computer when signing on from his house and nothing happened so it's definitely has something to do with our individual systems. =\
