I'm using ArcMap 10.3.1 from a basic desktop concurrent use license. The problem I'm experiencing occurs when I load an existing mxd (creating using 10.3.1), and then try to switch from data view to layout view. When I try to switch views, the program crashes. I have tried to delete the normal.mxt file and this has not solved the problem. I've also updated my video driver and run the ERSI diagnostic to see if my computer is capable of running the program. I've also run a diagnostic to ensure that my computer is not experiencing any issue with memory or drivers. Any ideas on what might be causing the problem or how to fix it?
Try running MXD Doctor "C:\Program Files (x86)\ArcGIS\Desktop10.3\Tools\MXDDoctor.exe"
ArcGIS Document Defragmenter "C:\Program Files (x86)\ArcGIS\Desktop10.3\Tools\DocDefragmenter.exe"
I have had the most luck Nkronck's answer. MXD files may become unstable over time and refreshing it by creating a new one is usually the quickest solution, however not always the case.
