Help! Lost savegames...

Hello,

Yesterday I snuck into Scapa Flow to see how it looks, but couldn't get out - took me three reloads until I went out without being killed. Well, after that and a couple of sinkings, I saved and went to sleep - but now this morning, when I selected 'Saved campaigns', the game is not showing any of my saves....
The savegames do exist on my hard drive (my documents\something\SHIII\Saves\profile name\0\savename.*), but the game refuses to see them.

Maybe this is related to SH3 Commander, which I installed after saving (but I am not using it yet) ?

How can get back to my savegames ?
Or should I just start anew (well, dead *is* dead)
