Hi there. I have Modern Warfare 3 on PS3 and I can't download maps on the PS3 store. I can purchase and download maps fine but then I load up the game try to play on the maps but it just says Piazza is missing or damaged but I have downloaded it. I this the problem might be the fact that I have the wrong code beacuse I got my game new from ebay but from a different country. I come from Australia. If my code problem is correct I don't want to have to buy another game so please help me Infinity Ward.
