Boot Camp Beta!

I'm have a big problem; I need to re-install an individual driver from boot camp onto my computer because the keyboard on my pc doesn't work. I was told to use the assistant to install an individual drive, but I can't do that because it says my boot camp beta is expired. Everything works fine on the mac side of the partition, but I can't type anything when I boot into windows. I don't want to upgrade to leopard just so I can install one driver, I think that's a rip-off. My question is, is there a way to re-install the one drive without using the boot camp assistant or is there something I'm overlooking? Any help would be greatly appreciated! Thanks!

its not really a rip off, it was beta software and expired support was Dec 31st, you cant expect a beta to work for ever.

do you not have the driver CD that was asked to burn?

did you try pluggin ina USB keyboard to see if that works, i recall bootcamp driver cd once installed into windows actually creates a directory on your C drive with all of the drivers copied to the harddrive on C, cant recall, but i think it was under cprogram files\mac drivers or something
