What is wrong!?!?
 

When I try to log and then click the project 1999 server, it brings up my character. But once i click "enter world" it takes me back to the log in screen. When i try to log in once more it tells me in a message that I lost contact with the server or to re-run the up-date patch. Please help me with what to do to get back on-line?

If shutting down your pc and restarting it doesn't work try creating a completely new character and logging in. Might give us a clue as to what's going on.

are you switching from account to another account? usually it takes about 5min for the server to be kewl with letting you on another account.
