We are experencing the following error while using Civil 3D 2008.
When opening a drawing, it gives an unhandled exception error with "Exception in C:\Program Files\AutoCAD Civil 3D 2008\AeccLand.dbx ARX Command" After closing that error, we receive "FATAL ERROR: Attempt to delete class 'AeccLandAPI' which still has registered descendants.
Any ideas on why this comes up? The program crashes only when a project file is opened. If the program is opened with the default template it doesn't error out?
