my brother and i are trying to play online against each other on FIFA 09, we exchanged each other IP address and when i press host and he presses connect a it tells us that connection has been lost that it could be do to that my opponent has a different version of the game than me? what is that exactly mean? we both have the north american version so i don't know what version type we have differently? my brother lives in mexico by the we way could that be a problem?
