I am running ArcGIS 10.2.2 on Windows 8.1. Las week Arc was working just fine, today, nothing. I cannot think of any changes, downloads, or updates that would have messed with it. I already tried deleting normal.mxt and the whole ESRI file in the roaming and local sections of the appdata area in my C file. I don't have much python or script background, but will instructions I will try.
Any assistance would be much appreciated. I am at a critical point in my thesis!
