Make sure your firewall isn't blocking access to SupportTool.exe. Anti-virus programs have also caused similar errors.

If you want to make sure they get the files you could email supportdos@larian.com, with a description of the problem and the report.zip file generated by the D:OS support tool. Alternately, just email with a description of both problems, and offer to send the report.zip if they didn't get the bug report.
