Tymzend,
What you might want to do when this happens again, is Try turning the Dual Display off. Then Run Hoster Play a song, then close Hoster. Once you have done this, Turn the Dual Display back on, then double click on your Singer Screen to send it to the TV, and see if that will work.

This would allow any registry settings that could be getting screwed up to be reset, when you don't have your 2nd monitor hooked up.
