AUTOCAD - Fixing corrupt user profiles

If Autocad runs ok in a different profile, you probably have a corrupted user profile and just need to back up any customizations, then do a reset.

Login using a good profile:

BACKUP:
1. START>All Programs>Autodesk>AutoCAD 2015>Migrate custom settings>Export AutoCAD 2015 settings.
2. Click the EXPORT button.
3. In the Export custom settings dialog box, select a location to save the ZIP file created by the program.


Login using corrupt profile:

RESET:
START>All Programs>Autodesk>AutoCAD <version> 2015>Reset Settings to Default

RESTORE:
START>All Programs>Autodesk>AutoCAD 2015>Migrate custom settings>Import AutoCAD 2015 settings.
Point the program to the file you created previously.

That should restore functionality.
