I'm also getting the following error when I try to save my configurations:
Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index.
If I click Continue, it allows me to save a txt file, but it is 0Kb and useless.
Quit works as designated.
