Wireless Mighty Mouse unresponsive in Windows 7

I went through the install process of Windows 7 on my late 2007 MacBook with my Wireless Mighty Mouse and it worked fine. When it was all completely installed, I could use the mighty mouse like perfect (even the right click would work!) until I installed the drivers on the Windows Install Disk. The minute the install of the new drivers finished, my mighty mouse didn't work. I couldn't add it in the bluetooth devices either. I have no idea whats going on.
