Need help- customer service unresponsive

I was totally in love with Booxter Lite and so I upgraded to Booxter. Then, sometime after the upgrade, I lost the ability to add new books. I know there is supposed to be a larger capacity than the 138 books I have in Booxter. I emailed the customer service number on the Deep Prose website and havent received a response. Bummer!
