??? Sign Pal - Jaguar 3 Plotter Driver ???

Some person came in my sign shop and wanted to sell me he's sign shop equiptment. The only thing that was any good was this vinyl cutter. So I gave him 350.00 for It. The problem Is it's called a "Sign Pal" - Jaguar 3. It is the same thing as my Panther 24 but has a contour cutting system on It. So I tryed the GRC-60 Driver and it cuts and when I go to contour Cut The light does not light ans only goes to Target #2 then stops. Anyway does anybody know what DRIVER I should use.............Thanks Phil @ printman716@aol.com
