What kind of error is this? Tell me if you can fix the problem and I'll send the map. Or maybe you can just TELL me how to fix it? :)

This Error comes up when I have compiled the map and are going to run it!

EDIT: I've found this string in the .err file:
hlrad: Error: Malformed face normal
Description: The texture alignment of a visible face is unusable
Howto Fix: If using Worldcraft, do a check for problems and fix any occurences of 'Texture axis perpindicular to face'

To check for errors, press ALT + P. This should help (I think it's dodgy geometry messing with the textures, possibly).
