Bluetooth mouse won't start

My "Wireless Intellipoint Explorer for Bluetooth" (what a name!) was working
flawlessly, then suddenly and spontaneously died about 24 hrs after
installing XP sp3.

Used the wizard in the bluetooth which seems to work, but no joy. When I
reopen the bluetooth pane in Control panel, the mouse isn't listed even
though I just installed it.

Removed bluetooth from Device Manager, downloaded new Intellipoint Drivers,
loaded them, reran the wizard. Still no joy.

Anyone have any ideas on restarting this balky bluetooth mouse.

Thanks
