[color:"orange"]Error copying savegames\game1\inv.b2 to dynamic\minventb.000[/color]

Check the saved game folder to see if inv.b2 actually exists. It is a zero byte file, so you can simply copy that file from a working save, or create a new empty file with that name.

Check the number of files in the saved game folder (in '..\Divine Divinity\Run\savegames'). Missing files might cause the game to crash when trying to load. A new game should have 22 files, after going to either Verdistis or the Dark Forest it should have 27 and after going to both it should have 32.

.0 / .x0 = Aleroth, Ars Magicana, etc
.1 / .x1 = Verdistis, Council Hall
.2 / .x2 = Dark Forest
