I get an error on loading the theme editor "configuration system failed to initialize"

Here is the log file it references.

It looks like your settings file got corrupted somehow. You can fix it by deleting all settings files. This will reset all settings to the default.

To do this go to this folder:
C:\Users\Spencer\AppData\Local\ATVO\

Then find and delete every folder that starts with "ATVO.ThemeEditor.exe_...."

Thanks very much! I was able to get it going doing this!
