A couple people have reported similar problems.
Please email supportdos@larian.com, with a description of the problem and the report.zip file generated by the
D:OS support tool. The report will contain some system information, which will hopefully help Larian fix the problem. It will also contain your saves, which are not directly relevant in this case, so you can delete most of them to reduce the file size (couldn't hurt to leave a save in the End of Time).
