The idea sounds great but the landing page could be so much more informative. Ignoring the testimonials and the looping video that's hard to discern concrete information from you are left with very little in the way of information to justify the expense. That's not to say the product isn't worth what you charge, it most likely is, just that I believe it's doing itself a disservice in convincing me to use the trial. If each one of your selling points from that 3up column section where it's own section with more details on how it works and how easy that particular feature is to use etc I think would do a much better job at convincing people.
I saw those pages, but they read like tutorials for people already sold into the idea and just needed help implementing some of the features. What I thought was really missing was selling the benefits of those features before trying to explain to someone the steps needed to use them. I think that's where the gap is on the landing page. As currently it goes from Short Definition of Feature -> Tutorial on How to Use Feature. I think what potential users really need to more content about why the feature is beneficial to them and a very succinct overview on how it works.
