I followed the install guide, ran the game... created my character, had to log out. When I logged back in, it took me to the old CoH login screen. I put in the username and password that I'd created, and it took me to a server selection list in which the only two server options were both gray. So, I closed the game down, came back later. Now it tells me my username/password are incorrect and won't let me log in at all.
UPDATE: I went to the account link here in the forums, and did a 'change my password'. This time, when I tried to log in, it allowed it, showing me the grayed-out list of servers: Torchbearer and Excelsior. I can't get back into the game. :(
