Netflix Error MS2105

The error you're seeing is related to the Silverlight plug-in, which Netflix uses to play TV shows and movies on your computer.

This error is usually caused by one of three things:

  • A computer setting preventing Silverlight from storing files it needs to play your TV show or movie
