Installed Ubuntu, now mouse doesn't work in Windows 7

before I upgraded from Vista to 7 I was dual booting Ubuntu 9. something and when I installed 7 I thought it deleted it, but now that the boot screen comes up again it's still there and works. Not sure if this could cause problems.

When I was installing Ubuntu 10 a window kept popping up that said my mouse was trying to communicate with the PC and that I had to enter the PID or PIN or something, but the window wouldn't stay open long enough for me to do that.

I've tried updating the mouse drivers and reinstalling it, but it didn't work. It was working just fine before this.

Update: Afterwards I deleted the partition Ubuntu was on, reinstalled Ubuntu 10 since the boot screen wasn't coming up, and the mouse works fine in it, so it shouldn't be a physical problem with the bluetooth adapter or mouse. I also tried using system restore, but it still didn't work.

I can get the mouse to communicate with the PC and set up, but it never works and usually shows up as not being active after I install it. Uninstalling and reinstalling doesn't work nor does updating the drivers.

I'm using a Microsoft Bluetooth Notebook Mouse 5000 and a Rocketfish Bluetooth Adapter.

Please help, using the touchpad sucks! How will play my precious games?

Well, I'm an idiot. I thought the pairing button wasn't working, but it turns out I just wasn't holding it down long enough. I could've sworn it used to work with just a press.

Time to play some vidya games.
