Please help

ive just downloaded a game thats on 3 discs ive copied them fine with blindwrite and the game has installed fine but when i try to play it it asks for the cd and i try all 3 cds but it says wrong disk inserted is it any thing 2 do with some of the cabs packed in winrar i cant seem to unpack them

Could you please give us a bit more info on this game. At least, I assume you wouldn’t ask help on an illegal download and get this forum in trouble with the authorities?
