Help! – Audiobook Player SmartBook Review

I like the idea of this app, but I’ve only just downloaded it and already there’s a problem. The pro version is supposed to be free (for a limited time?), but each time I hit the upgrade button, the load symbol whirs, disappears, and then nothing. I know I should be getting a dialogue box from the App Store to confirm what I’m doing even if I’m paying nothing, but it’s not there. And the only way off of the page is to cancel the upgrade. What gives? Also, this seems to be the only way to actually contact the developer. Clicking on App Support on the store page sends you to his blog page, not an e-mail destination. I’ll be very happy to change the review if these problems can be resolved. Thank you.
