Need help adding a computer to a wireless network.

Question

Trying to add my dads computer to wireless network with WPA-2 protection and forgot the password so can't authenticate so I'm trying to do it using a USB thumb drive but that is not working. I am trying to do the thing where you save the wireless info on the drive and stick it into the computer I am adding but it says that the Wireless network setup wizard does not have enough info to run and try again but it works on other computers. He is running Windows XP with Service pack 2.
