New Version Won't Install... – Lick of the Day Review

I have the previous version of this which I like a lot. When I try to install this version on my iPod, iTunes says it won't install it because it needs a newer version of iPod software. my iPod is the current version - Just updated iTunes - everything's the latest, don't get why this won't install / update to new version. ???
