Sorry to bother, but I've searched and can not find out what this error is or how to fix it. My ACAD C3D 2011 was working fine yesterday and for the past 4 hours this morning, it opens to command then this error appears closing the program. Behind the error notice the drawing is showing, but of course I can't do anything since the program is shutting down. Not an equipment problem, been running the same computer, drivers and programs since C3D was installed originally.
