Game freezes when playing
 

I played nice since the day i bought the game, then upgraded it to v.1.1 and all gone fine... never had a problem with it and neither with other games.
In the last couple of weeks, i haven't touched anymore SWB then, today, decided to jump in the arenas again, but here it came the surprise: the game freezes after about 20 secs of play and the hd begins to work on and on... forcing me to reboot.
I tried both single and multiplayer events and the problem is still present.
