Fixed some players starting on insane difficulty

[p]Patch 1.04d: Fixed that some players, who had last played the demo on insane difficulty, would start the release version still on insane difficulty, and be unable to change it. [/p][p][/p][p]Please let me know if you still have old demo difficulty issues, or if this fixed the issue for you.[/p][p]-Lasse[/p]
