The plugin MarketPress breaks my theme

Hello. I first install the MarketPress Lite plugin and it works great. But I want to use USPS live shipping so I purchased the upgrade to MarketPress pro. I use Faded Theme by Mint Themes and it has a home fader that works like a slide show of my products. When I activate the pro version it breaks the home fader. The images stack on top of each other. I really like the Faded Theme because we are a band and it is on our home web site, spilledmusic.com. Our store is a sub domain. I have 2 store sub domains. One is for testing plugins and themes. Is there a way to break out the USPS live shipping option as a plugin for the lite version since I purchased the pro version and cannot use it?? Thanks. Tim
