[Greg McKaskle]

Due to a manufacturing mistake, the DVDs sleeves were given unique serial numbers rather than a common one. The licensing was setup for a single serial number, not a long list.

The correct SX serial number was printed on a card that was in the packet, but it is in a rather small font. These were built overseas and by the time it was discovered there was not time to correct it.

It has been a bit support issue, as you can imagine.
