Plus Voice Command for Media Player Don't Work right

hi, i have Microsoft Plus for Windows XP. I have installed it on my new laptop i had two days ago. I open Plus! Voice Command for Windows Media Player and i can say "Media Player, Play" into the microphone and it will play but if i say "Media Player, Play Artist Linkin Park" then the program hangs and Windows error handler thingey comes up. This happens every time i say that command but i am not sure if it does on any others. Can anyone help?
thanks, dandono.

edit:
i am using Media Player 10. XP Home Edition SP2.

OK Every other command works exsept the "Media Player, Play Artist" one. does anyone know how to fix it? thanks, dandono
