Cannot load the game

[Mesocyclone]

After trying to load the game via the 'execute as administrator' (right mouseclick on the Penumbra-icon, then there appears a pull-down menu), I don't know the exact term, because I have the German version of Vista, I translated this from German. Then I got a window with the name '@ctivate' to fill in the code.

Yep that's what happens in XP here to, but it fails to do this in Vista64

Well the XP/admin trick didn't do it in Vista either, so I'm out of options for now...I blame it on Vista(64) compatibility (activation) for now.
