I am using AutoCAD Architecture 2012 x64 on Windows 7 and just recently, anytime I try to insert items from the tool menu (walls, doors, windows), either nothing will happen or the program will crash. When I select a door or window from an existing drawing, the AEC parameters do not show up, instead the properties only show what looks like data for a block.
Any idea why this would happen? A bad AEC .dll? Reinstalling the program was the only way to fix it, but now I have to reconfigure my cui.
