Whenever I try to load the game it'll generally get to the first screen, but everything is very, VERY dark or utterly black. After a few seconds, the entire thing will freeze, generally taking my computer with it. I found the supposed fix for that in the sticky, but I can't open the r3dopengl.cfg file to edit it! I tried opening it in AppleScript, which didn't work, but it's now set as the application to open that file in, so I can't try anything else.

BLEH. Any suggestions??
