Camquest won't load

Anyone tried to use Compcam sponsored camshaft selection software today called "Camquest". It won;t load for me, just spins the idler wheel in the center of the page and continues to read "0%" and makes no progress. Something did load but my macbook is reading it as a text file. It worked without a hitch in the past. Thank you.

Update: Let me answer my own question, Camquest does not work on macbook, I must have been using a windows system in the past but forgot about that minor detail.
