OK.
Dude.
Slow down here.
You have a friend who has a *working XP installation* with the low-IBX version?
You cannot simply copy and paste the IndivBox.key file into another computer, that defeats the whole point of INDIVIDUALization
However, can you ask this person nicely to make us all a VMWare image from the installation? As long as he doesn't upgrade WMP it should work fine and let us decrypt stuff again!
