Thanks all. I just reloaded it and it worked fine. I will use your suggestions Werdo64 when I get home. Right now I'm trying to get my laptop to run the client, but I'm at a hospital and that may be an issue with its ISP.
I just loaded up the game, created my character, got to the spot to begin playing, and then tried to use windowed mode. The screen went black and that's it. I shut down the game, restarted it, and go right to a black screen with music playing. How can I go turn off this mode in the client so I'm back to where I was before I clicked windowed mode. I've tried alt-tab and that doesn't work. Thank you!
