Thanks, Sofie, for your response. I downloaded the complete formula collection. After I copy a UPR to UF3 it finds the enr-flame file. After I click ok the warnings I receive indicate errors trying to compile and then dozens of "cannot locate parameter" messages. What I end up with is a solid block of color. Both programs, UF3 and Apophysis seem to work normally in every other regard. Could it be some setting in the options of either program that are basic to the rendering to occur that I may have to change?
