I haven't been able to log in at all yet. I first attempted to open the game through the launcher, but after appearing to load the game, it hangs. The music still plays, and the Version message appears in the lower left-hand corner, but the screen remains blank and I have to reboot the PC in order to close and get back to the desktop.
Launching from the client exe directly allowed the Cryptic Login Protocol screen to come up where I can make changes to the Options, et al. and attempt to log in, but after about 3-4 minutes of "Connecting to the account server..." it returns to the log in screen
Edit: I finally managed to get in. After setting the "Windowed" option through the game client log in screen, I was able to see that ZoneAlarm was blocking any further action by the client until I allowed approval, but now I am stuck with an extremely long download.
