Over the past several days, this error has been causing me headaches on two machines. Pops up on print, autosave, or _quit, as well as some other commands. I have clicked multiple times to report to Autodesk, but to no avail. Any ideas would be most welcome. We are running Autodesk Civil3D on Windows XP Pro with plenty of disk space and ram. DWG files are stored on a network drive, Windows SBS2003. Thanks, -PJ
