The problem is when I try to start Tremulous, its fine, but when the map changes, I get the message:
ERROR: can't find menu3 ....etc... or something of the sort.
Then, my brother tries to play, and the screen goes white, and doesn't change.
Any help would be appreciated.
UPDATE:
Now, when I try to run Tremulous, screen turns white and nothing happens.
It started with Volt HUD, then I tried installing another HUD (simplicity.) and the same thing happens.
