One of my coworkers emailed me about some issues with opening .mxd files in ArcMap 10.2, and through further questioning she revealed it actually started when she updated to 10.1 and has continued after her update to 10.2. Apparently when certain mxd files are opened (I'm guessing ones that were created before her upgrade to 10.1) in ArcMap it crashes with an error (fig. 1). If MXD doctor is run on the files they then work fine, I have attached the Diagnostic Report(fig.2).I thought maybe if they are just older 9.xx documents this could be the culprit but I read that those mxds should still open but will just be saved as 10.x map docs. Any idea looking at the errors what the problem may be?
