Our User gets this error when closing a file that was utilizing the Basemap services from the ArcGIS for AutoCAD Plug In. ​

Any solution?

I was getting these errors too. However, this was not a ArcGIS to AutoCAD Plug In problem, it was an AutoCAD version problem. This error came up because the .dwg was from an older version trying to be edited in a newer version. I am not sure if I saw a fix for the issue though.
