I have problems with my public file. I have downloaded the whole collection of public formulas, the program has installed them, but when I acess the public file for formulas, coloring algorithms, transformalation, the files are empty. I have redownloaded the program again, did the whole process, but the problem is still there. My copy of UF 4 is purchases, it is not a trial copy. Can somebody help me? Many thanks, Josette
