AutoCAD Civil 3D

[#1]

On opening a C3D 2013 drawing, C3D hangs for about 5 minutes.  At the bottom of the screen is the message: "Upgrading COGO points".  This drawing is only 974KB. 

The drawing is being opened from a network . I tried saving it on a local hard drive.  That had no effect.

Could the dwg file be looking for a point file that may have been erased, moved or renamed?

Here is my check list to see whats going on.

1. run a RECOVER command or the RECOVERALL command on the drawing
2. run -PURGE ( select Regapps) command on the drawing.
3. if you are signed into your Autodesk 360 account but not using the cloud turn off the Enable Cloud stage
4. Make sure your data shortcut is linked to the right project.
5. Check xref links
6. Turn off Hardware Acceleration option (3dconfig command)
7. If you are not using the Survey Database features turn off in Toolspace and make sure its not linking to a project
8. Open windows task manager and see if you have misc Autodesk application running such as AutoCAD Download Manager, Atutodesk InfoCenter, Aec32bitAppServer.exe, Content Services.
9. Last try doing a repari on your C3D

This happened at least a dozen times while I tried various solutions this morning.  This afternoon after lunch I opened the drawing again and it opened almost instantaneously.  I changed nothing from when I closed the drawing this morning to when I opened it this afternoon.

Thank you all for your help.
