XP Mac Drivers install - lost usb use Please help!

I have just installed XP Via bootcamp, all was going well, until I started to install the mac drivers from the cd.

It got to the point where is asked about the graphics card (have got imac) then for some reason the mouse wouldn't move, nor the keyboard have any effect, it;s almost as though the drivers for the usb have gone, the mighty mouse still lights up, but it;s static on screen and no keys work on the keyboard!!

Please help!!!

O I managed to get it sorted, I just wiped the partition in OSX and started again, when installing the mac drivers cd I kept moving the mouse around and after a few sticking points it worked!!!!

I am now running Battlefield 2 all specs on high!
woooowee!!!!!!!
