i have problem i own Fallout 3 (not GOTY) and i tried to install it but the CRC error appeard (menuvoices.bsa /meshes.bsa /B13.bik doesn't match the file in setup's.cab file. The medium from which you are running the setup may be corrupted...). I tried to install it on my PC (XP SP3) and Notebook (Vista Home Premium). The same problem here. I read a lot of topics on a lot of forums but nothing worked for me. What am i supposed to do?
I beg u pls help

It sounds like either your DVD drive is having problems or the disc is damaged. CRC errors usually only appear if your computer can't read data from the disc properly. Make sure you disc is clean and that there are no scratches, as those are the most usual causes for that error. If you just bought the game recently, take it back to the store you bought it from and they will give you a replacement.
