At our offices, we have liscenced versions of AutoCAD 2002. We have had legitimate liscences for Autodesk products since release 10. However, I keep getting the "Produced by an autodesk educational product" stamps while plotting on one particular drawing. This drawing was set up at our offices but has blocks from an online ressource, I believe it was Cadalyst or similar. This error only happens in this drawing. Also, I tried wblocking it out, even creating a new drawing & inserting, but still the stamp goes with it. How does this work, is it attached to every entity in that drawing now? I even tried removing the blocks beforehand, to no avail. This drawing has several hours of work on it... how do I recover my drawing? Is there a way out? thanks d
