Where to reinstall mouse drivers

[Epiphron]

I'm having strange mouse issues lately. With the magic mouse, any scrolls and multitouch gestures do not register. Better touch tools even gives me an error that says no mouse driver for the magic mouse. When I use a regular mouse, the scrolling wheel doesn't even work.

Anyone else had this issue?

yes, I'm having this problem. It's like the drivers have disappeared. The control panel in the System prefs does not have any gestures on it. It's OK on my cloned system.

I done a search but I can't see how to redownload the drivers.
