AutoCAD Civil 3D

[#1]

I got the first attached message regarding UNDO command which I ignored. The second attached message then came and my UNDO command was frozen. I lost a lot of work done after I have shut down and restarted my computer.

Who knows what I should have done after the first or the second message?

Hi,

Save the open files with new filenames, close the drawings, close AutoCAD and restart all.
