That is very strange... I'd guess a corrupt objects.000 file (in the '..\Divine Divinity\Run\static' folder) is to blame.
There is a file verification procedure in the
Troubleshooting Tips topic which can identify any missing or corrupt files, which can then be replaced or repaired.
You can post the results of the FileCheck program here, but I'll assume the objects.000 file mentioned above is at least part of the problem, and give a
download link (83KB) for a known good copy. If your objects.000 file shows up as corrupt, delete or rename it, then download mine and unzip it into the 'static' folder.
