I bought Digital Art for the C6 Pro, and registered it on Daz with the same code; if they don't recognize that for the upgrad (IF I wanted it) why the heck did I bother?  Eh, oh well.  16 bucks is better than full price for the program-no complaints here.
 

Wonder if I can get a rebate on the C7Express I got earlier, then?  I'll have to find out.
