App did not work

I could not do anything with this app on my Mac. I then purchased the Photo Stitcher App for around the same price and that app work well for me, I was able to scan my 12x12 scrap album sheets on my 8x11 scanner and the Photo Stitcher App was able to merge the 4 scans together seamlessly. I now have all my 12x12 scrap albums digitally on my computer.
