Media Center and MusicMatch

I have Media Center installed on my PC. Anytime I try to use the Media Center
or the Media Center Extender to play music it asks me to sign into my
MusicMatch account. Is there a way to set Media Center so that it
automatically signs in?
Is there a way to set MusicMatch so that it automatically allows Media
Center to access my music library?
Its a pain to be in my living room and have to run back into my office to
sign into MusicMatch so that the Media Center Extender can play music.
