I am using Mechanical Desktop 6 Power Pack. The person that loaded AutoCAD had a whole bunch of toolbars and menus added that I didn't really like so I unloaded the menu files and was working off of the standard ACAD menu file. I think that the menu files were a mix of standard MD toolbars and his custom ones. There was one thing that I liked about his TB's and it was that he had access to a hardware library. I don't think it was anything custom that he created, just standard hardware libraries that come with MD 6. In order to have access to this library again I reloaded the menu files that were originally loaded when I started using this computer. Everything seemed to be working fine but then MD crashed. Now when I try to open it I get to the opening screen where I can either open a drawing that I've previously been working, open a template, or create a template etc, but as soon as I select a drawing to open it crashes again. The wierd thing is that one of MD's toolbars is still visible. I don't remember which one and that's the only thing you can see that has to do with MD. Everything else is gone except for this one toolbar. Any ideas on what happened and how I can fix it?
