Vista - intellimouse & intellitypepro bluetooth

I've installed since long time the subject microsft products and was very
happy with them until yesterday.
I tryed to transfer some pictures via bluetooth and since then intellimouse
& intellitype doesnt work anymore. I have try to reinstal-it again but
whitout success, still dont work on this machine.
I've installed the mouse and keyboard in another machine and it performs
perfect.

Can please somebody hepl me in this matter? The only thing what I don't have
try is to manage registry information only because i don't know where I have
to look for!
