Trouble with bluetooth mouse (Boot Camp)

Hey! I'm in need of some help for my Dell BT Travel Mouse.
I just bought a MacBook Pro about a week ago, and installed WinXP SP2 through Boot Camp. Everything has worked fine up until this morning when my BT mouse suddenly stopped working on both Mac OS X and Windows.

I fixed the problem on the Mac OS X by trashing a preference file, and the mouse now works perfectly.

It still does not work on Windows, though. When I try to install it, it locates the mouse, connects, but the system tray displays the following message: "A problem occured during hardware installation. Your hardware might not work properly".

I have a feeling it is a software problem. I tried reinstalling the Boot Camp software, but it didn't work.

Does anyone have an idea what I should do?

Thanks!

Uninstall it and try reinstalling the windows drivers?

I'm having the same problem, which preference file did you delete? Have you solved it on Windows?

Thanks!

Have you tried updating Boot Camp to 3.1?
