Lately I have been backing up my games to .mds using Alcohol. Painkiller's play disk would have taken 6 days to back up due to all of the errors, so I resorted to downloading it. I have downloaded the play disk probably 5 times now, they have all come in .bin format. When I open the .bin in IsoBuster it only shows 1 file, "PainkillerSetup.003." When I try to run "PainkillerSetup.003" windows doesn't know which program to run it with. Any ideas? Thanks for the help, I hate having to download something I already own to back it up.
