Won't download... Please fix, would love to try then buy! – Between the Lines Level 1 Lite HD Review

This looks like a great app, but I wanted to check out the free version before buying the full (and expensive!!!) version... If this one doesn't work, won't even install! it says a lot about what the full version might be like--- please fix!
