Okay, I know there was an update last night, regarding the chat and everything.
I logged on today around 11:30 EST, and It was fine for about a half hour before it disconnected me from the server.
It's now either saying "Failed to connect to main server" or is stuck on "Request accepted, sending login. I don't know if this is caused by my own computer, or by the update, but I would appreciate help for either. Thanks in advance for your suggestions.
