When I opened Stardraw 7 today, there was an update available. I updated and restarted. After starting a new drawing, I tried to export it to AutoCAD but got an error with the following details...

Any help would be appreciated as I need to bring my drawings into AutoCAD for incorporation into a larger drawing set.

The following details will be sent to Stardraw.com Ltd:
