Switching from marketpress back to marketpress lite

I originally installed MarketPress Lite on my website (thehormonehandbook.com) and upgraded to MarketPress with the paid subscription a few months ago. As it turns out, I have not used the features that come with the paid MarketPress plugin, so I would like to switch back to the free version. Will I lose any product data or order information by switching back? Do I simply deactivate the Marketpress plugin and activate Marketpress Lite, or is there more to it? I see on your website where I can change my subscription options. Before I cancel, though, I am afraid of losing my settings, order history, and product inforamtion if I switch back. Looking forward to hearing from you.
