Men of War - playing old saved games with new patch
 

Love Men of War,despite patch problems (now solved) but now I can't load my old saved games (and being most of the way through all the campaigns I don't really want to start again).
I'm sure I read somewhere about a fix for this - can anyone help please? I've scoured the existing posts but can't find anything, and I'm sure others have the same problem and would welcome some help.
Thanks in anticipation
