When I complete the first mission in the first campaign, the game loads the second one, when the loading is complete everything freeze! The mouse cursor no more moves and the only way to get back my Mac desktop is to Cmd+q and kill the process when prompted. I'm so sad about this... the first mission was flawless, with no sign of bug!
I tried to download a profile from another player, to try another mission of another campaign, but the result was always the same. And the same happen in the expansions.
I've installed the latest patch and used the trick for the white screen. Everything goes fine until the loading of any mission except the first of the first campaign.
