Using ACA2012 mostly as if it were regular AutoCAD, no Project Navigator, no AEC objects, etc. When opening several of the files for what appears to be only one project the program gets all the way to the drawing appearing on the screen and then a message pops up saying that the program is not responding. No other users appear to be having this problem, and ACA2013 is able to open these same files but saving down for the other users would be a huge issue.
I've attempted to use the repair utility as well as several uninstall/reinstalls including one with the automated uninstall program from the Autodesk website, all to no avail. Does anyone have any suggestions on other things to try? Even if they may seem obvious I'll take any help i can get
