Why cant i see the pictures when i open textures...by pressing "t". All i see is black and red little boxes???Get back to me...

erm...do you have quake installed? Or whatever game you're using Radiant for. Sounds to me like it can't find the path to the default textures for some reason. Then again, I haven't played with radiant in well over a year and a half. You may be better off asking in a more specialized forum. Sorry.
