Thank you Raze for the very kind reply!

Um... Too late now... I unistalled the game and the savegames seem to be gone. I could have in fact backed them up, should have, but well... the intellect came with the evening train.
I also have the slight quirkyness of running XP on Mac which normally works quite OK but I know it is not the standard combination.
Once I get the game running again, I think I will find a way to find the positive on the fact that I shall know how to level up more to my gaming prefences etc.
Guessing from your "timestamp" - were you a fan of the original divinity, perchance?
