Hi top spin lovers! At last 3 month I can't play TS3 normaly. Game freeze after few shots at 85%. I try everything, put my PS3 in DMZ mode, open ports, which TS3 need, but nothing works

Also, I change my router and internet provider. No result. Other games ( GT5 and others ) works perfectly, TS3, no. I realy like to play the tour, but not this way. Maybe everyone know any solutions? What situation with xbox?
