Sony Vaio Event service has stopped working

Hello,

I have a sony vaio vgn-cr series, and for some reason I cannot get my FN key to work. I have tried to start the vaio even service through the services window, however when I do I get a dialog box from windows vista stating "VAIO Even Service (Service Module) stopped working and was closed"

What should I do? I have been to the sony website, but I am unsure if I should download any of the driver or software updates.

Thank you in an advance to anyone that help me with this problem. =)
