sorry, but i think i've found the problem. it seems that one of my pk4 files is corrupted as i can't extract the contents (for faster gameplay
) and the no-cd crack works with the doom3 demo with a few glitches.
but strangely though, i can play without the no-cd crack (with a very slow fps), but when i use the no-cd crack, the same error happened. anyway, i'm taking the cds back to the game shop for a change of cds.
thanks anyways!
