I have iso files of Medal of Honor Heroes and SOCOM Fireteam Bravo, each downloaded from multiple sources, which have dealt with freezing issues. What happens is I attempt to click on the campaign mode button, the game proceeds to freeze for a second or two, and I am left in the same menu. What could be the possible explanation for this. Every other game I attempt to start works fine. PS: I have 6.60 pro temp firmware.
