Thank you for the reply, but I forgot to mention that after I go to XMB and try to run the game, it installs an update of the game at first (i tried it with Borderlands, Ninja Gaiden Sigma 2 (plays only the intro movie) and Assasin's Creed Brotherhood) or it doesn't install anything at all (Bayonetta, Trine) then the screen goes black and freezes.
The only game I have been able to play is The King of Fighters Xll and Flow(which is about 200 mb and I installed it from a usb stick). I use PL3 MOH. Is there any way I am doing smth wrong?
Thanks in advance.
