Ultranav stopped working. How to fix it?

[phil81uk]

I finally get everything (almost) working on my X301 with Windows 8. I got it all working on a spare X301, and when it was done I moved the hard drive to my main X301. But when I did, the scrolling mechanism, where I hold the middle ultranav button and then scroll with the navigation nipple, stopped working.

I tried uninstalling the Mouse driver under Devices (there's only one mouse, and no mouse plugged in so figured it's that).

I tried installing:

Is there anything else that I can try?

Ignore that..... I'd installed the 32 bit driver....
