I encountered a problem: Error when launching Heroes 6 (licensed version) on Nvidia GeForce GT 440: - You launch the game / it starts searching for updates / the UbiSoft launcher screen appears / the client is logged in, everything is fine / you click the "play" button / a picture appears in the center of the screen, the game loads, then a black screen for about 10 seconds, then it crashes to the desktop and that's it! The application is still in the task list, but it doesn't respond...
