To reset go to C:\ProgramData\Team MediaPortal\MediaPortal\MediaPortal.xml and delete the section with the name of NetflixWrapper.
In the version I am working on you will set this in the configuration section of plugins in the main configuration tool of media portal.
Ok, in that case can you PM me the logs so I can try and workout where it crashed.
Real life is taking its toll, I am slowly progressing but have not had much time and I needed to fix the internals That will teach me to not start off with a clean object model.
