If the crashes seem to happen more frequently when crossing through doorways, try lowering (or even disabling) hardware sound acceleration. This will be slightly different in the French version of Windows, but click Start | Run, type in dxdiag and hit Enter, then switch to the sound tab to get to the hardware sound acceleration option.
Did you install any programs or update any drivers, etc about the time the game started crashing?
Try deleting all of the files in the '
..\Divine Divinity\Run\Dynamic' folder. Since you have the
patch installed, if you reset the configuration files at least once after a crash when prompted, the dynamic folder should already have been cleared.
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.
Try backing up your saved games, just in case, and doing a clean reinstall of the game and patch. See the
Troubleshooting Tips topic for details.
