I had the same problem.. I download the PC version but I believe agnes got the files mixed up for I deleted the so called *PC file and downloaded the MAC version instead (I'm on a PC)...It worked! I think agnes reposted some of the files hopefully corrected the problem but I'm not sure.. I can't say if you download the MAC version now it will work on the PC but it did for me.. Just a mix up I think.. ~Cindy
