[EpiData-list] problems downloading to Mac OS X 10.6.8

HI,

I attend college in CA and my professor insists that I use Epidata for our quantitative analysis. I am taking a research tools class. Everyone with Windows was able to download Epidate, except me, the only Mac user. Actually, it downloaded or appears to have downloaded, but I am not able to open it up. When I try to open it up, it looks lke a corrupt document. It's not acting independently as a software program. I appreciate your help and aide.

Sincerely, Mic
