I have tried to run the game in two different ways. When I just click on the "Start the Witcher 2" icon it shows up in the menu bar at the bottom of the screen and then disappears with nothing ever happening. If I go into the bin file then launch via thewithcer2.exe then I get a message saying there has been a serious error caused by a deficiency in wine. I would really enjoy to be able to play this game so any help would be greatly appreciated!
