My menu bar went missing for some reasons when I was using my program. I have restarted and then changed menubar default to (0) and (1) but it still does not do anything. I can only see the express menu in there. I am using AutoCad Civil 3D 2009 as AutoCAD. I am not doing anything when it disappear. Is there a way to put it back? I've upload my a print screen to better undestand my problem. Thanks.
