Hello, I'm getting a problem with running QuakeDS 2. It will start up fine, but when it starts up, there are no walls, ceilings, floors, things of that nature. Also the menu (When you press Start) doesn't come up. The games freezes and then a line goes through the middle of the screen. I have to press a different button to get it to unfreeze. I am using an R4DS and an EZ-Flash 3-in-1 expansion pack. Can anyone help? Thanks!
