A couple people have run into this problem. Unfortunately, I have not seen any reports of a solution (it has been awhile since it has come up, though). You may want to email support@larian.com, if you haven't already.
AFAIK the patch would have to come through the online distributor (either the 1.03 patch or the upcoming patch, expected about the same time as the FoV/DKS release, next month); the patch downloads for the DVD version are not compatible.
