Left 4 dead weapon scripts?

Ok, i recently downloaded doku's mod for left 4 dead about 1 week ago, and when i decided i didnt like it, i open the restore file, so it restored everything, now it says that my oxygen tank, propane tank, and gascan are modded when i try to join local game servers. Can someone give me a link to what the original scripts are, or to download something that restores weapon scripts?
