I used the demonstration version of the 3D graph control to do some programming. We have now purchased the full version of Measurement Studio. Before installing the full version, I uninstalled the demo version. The next time I opened my project, I was asked if I wanted to convert it from version 1. to version 6.0. I said yes, and when I open my resource files, the 3Dgraph objects no longer show up as evaluation copies. When I run my application, however, the "Evaluation Copy" is still displayed in the control. I then uninstalled the full version, manually unregistered cw3dgrph.ocx, deleted it, and then reinstalled the full version. I get the same problem. Any ideas? I am using MS Visual C++ 6.0 and Windows ME. Thanks.
