You'll need to go into Device Manager on the PC and delete the Unkown Hardware (it should be unknown since you didn't install any drivers when it found it) that will have a question mark beside it (?) in big yellow. Next time you reboot with it plugged in it will again find the device and you can direct it to the drivers. Or you can just go to the Unknown Device in Device Manager and look at it's properties then tell it to Update Drivers and direct it to the drivers. Your choice, either will accomplish the same thing.
Damn! Beat by seconds
