If you reboot and try loading the game, does it lockup again?
Try deleting all of the files in the '
..\Divine Divinity\Run\Dynamic' folder.
This folder is used as a cache for the game. Files are created / copied there from the save game folder when you load, and written / copied from that folder when you save a game. The files will be re-created as required the next time you start Divinity. If there was a corrupt file in that folder, deleting the files should fix the problem.
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, after going to both it should have 32, after getting to the wastelands it should have 37, and after getting to the Black Ring dungeon it should have 42.
Different file extensions are associated with different areas of the game;
.0 / .x0 = Aleroth, Ars Magicana, etc
.1 / .x1 = Verdistis, Council Hall
.2 / .x2 = Dark Forest
.3 / .x3 = Black Ring dungeons
.4 / .x4 = Wastelands
