While your version may be english it appears to be the EU version. As I purchased my version in North America, I have had no problems with the 1.03 patch. Also my first question would be - Did you try the AutoUpdate before you applied the patch or after? If after, I would uninstall the game and patch. Reinstall the Game. Then start fresh with the autoupdate and see what it says.
Notice on the official website at:
http://www.divinity2.com/index_eng.htmlThere are at least 2 different english language versions?
German Patch 1.03: Download (1,87 GB)
French (plus US) Patch 1.03: Download (876 MB)
English, Italian, Spanish (plus US) Patch 1.03: Download (406 MB)
Notice that the French has US, also the bottom multi-language has US.
I would at least try both of these if you have not already.
Sorry if the above does not work out for you, I am just a gamer like you, not a official forum or Divine Divinity 2 Rep.
