(adsbygoogle = window.adsbygoogle || []).push({}); Hey guys, I'm trying to get MW3 to work on my friends PS3. I downloaded the proper duplex version, installed the fix, everything loads fine. But when I go to a private game or to play online it loads and I get an unkown function message. I don't know what else to do. internal and bd mirror are checked. the game loads fine, but I get that message, any suggestions?

Do you have any modded files?

No I do not
