I've been playing the game since beta, never got the disk just got a cd-key/ download from Direct2Drive (Bought from there). Awhile back I put in a few sound mods and I did make a backup of my Vehicules folder. Really can't stand the sound of a few cars that I used to drive a lot, and I have no way of getting the original sound files without going out and buying a new disc. Does anyone know where I might be able to find a original Vehicules Folder to download? Would anyone be willing to upload one somewhere for me? Would be really appreciated have some rewards for anyone willing to help, cheers :)
