Lynn - I think there should be a XLN registration code either in C3 or your cake store account. Register that with XLN.

so when I update I get choose 3 adpaks,  plus 3 midi paks  and 3 kits is this true

As I found out by looking further, this is true.  The downloads were on the xln installer, which I found by scrolling down and clicking on the producer bundle and using the registration code from the Sonar command center.  This made me very happy, as I have come to regard highly the AD drums.
