LaserSoft Imaging

I have received an e-mail Christmas offer of a 50% discount to buy an additional scanner licence, but I can make no headway in following this up. I hold a licence for a Microtek flatbed scanner. I would like to take advantage of the Christmas offer to buy a licence for my Nikon Coolscan IV ED. I cannot find which LaserSoft product is available or will work with my iMac running Snow Leopard operating system OSX V.10.6.8. On the pages for ordering there is no recognition of the special offer, and inputting the serial number of my Microtek, it is recognised but identified as for a different scanner. That is the whole point of the exercise!
I need to know a) What software is available to use my Nikon scanner with OSX 10.6 and b) if, and how I can apply the Christmas offer to it.

Dear Ancestor,

SilverFast version 8 is available for your Nikon Coolscan IV.
