When i was messing with my G5 and MX518 the setpoint software automatically updated and swapped drivers for me right when i plugged them in without having to press anything. I havent had this problem before but have you tried shutting down, remove the mouse, boot up and then finally plug in the mouse when windows is done loading so setpoint can identify it?
Have you tried the "check for updates"? It is in that tab under the circled I in the top left.
