Avast ye scurvey dogs! Yo ho ho and a bottle of rum!

The Interlink controller is Knife Edge's way of copy protecting their software. Any copy of the sim that didn't come in a box with the controller is not considered a "legitemate" copy. If your "friend" installed his copy on your computer, he'll need to bring the Interlink with him when he comes over to your house ;-)

Also, what was done for a serial number? Now that the online updates are becoming SO important, the registration and serialization need to be legit as well...
