Software Download

I missed the Oct deadline and went to work on my taxes only to find everything gone. Its telling me to upload my tax info from desktop software. So I purchase the Home and Business. But I only have an IPad to work from. When I open my download, it does nothing... just a black screen with a few words typed on it.. When I try to access my download thru the turbo tax website, its nowhere to be found... what am I doing wrong???
