There could be a problem with one of your dbf files. Have you made any changes to the dbfs?

i have not changed anything myself i did download 3 rooster files from this site though. im going to delete them and reinstal the game for the 3rd time

oh yes but i also am trying to play the game with the original rooster anyway just for some info.
