can't update to bootcamp 2.1

I had the same problem yesterday after reinstalling Vista Ultimate on my bootcamp partition after a hard drive swap. I could not upgrade from 2.0 to 2.1 via Apple Update Installer program. It would download and then I would get error when it would install. I then noticed that trying to open bootcamp manager was futile and Fn keys were broken.

I cannot pinpoint exactly what I did to resolve it however I will tell you some of the things that I did that seemed to have worked. For one I downloaded a few Vista required updates (by accident actually). After multiple attempts at downloading, installing and then redownloading bootcamp 2.1, I simply uninstalled all the bootcamp drivers, then manuallly downloaded the 2.1 update from the Apple site and reinstalled, rebooted and its seems to have worked. Something a little gltchy going on.

Now if I could only understand why I cannot connect to my work's WEP access point via the passphrase, Ill be golden. god vista blows.
