Most version mismatches are caused by not having the latest patch installed (2225). Try to make sure your running the latest in the patches and bonus packs and you'll save yourself loads of trouble and time online.

i re downloaded the 2225 patch and installed it but it keeps going

strange because I played a match (antalus) it worked well.
theni tried a duel(CUT2)it started downloading things and at the end it puts the message (the backscreen stays black)
