Are your game versions matching? Check that on the main/settings menu in the corner of the screen. Also, are you sure that your opponent (or you :P) isn't using a trainer or any tampered game data files? This could quite easily cause a mismatch. I would probably suggest you both reinstall the game and make sure you are patched up to the latest version. Once you have ensured all of that is in-place, you should have problems.
