I have really strange problem with saves - sometimes (and it is often) all saves are "converted" to older version and also it is not possible create new save (game looks like that save was created, but when i want load it, the save doesnt extists). Only workaround to "turn on" possibility to make new save is load some old save or restart whole application - but it is only temporary solution and i lost progress in game - and it is annoying :(

So please have you some advice for this problem?

I have Windows 7 64bit Professional. I always run MM6 as ADMINISTRATOR. I also try re-install game but it doesnt help.

PS. also this problem cause crash of game when I want move with party from one area to another - and it doesnt matter if i use coach, ship or only on foot...
