marketpress ssl admin area...

Hey guys, I've had an interesting development...whenever I start a blog or site I feel has long-term potential I like to secure the wordpress admin area with ssl just in case since I know that after the site reaches a certain size and popularity, it becomes a target for hackers.

However when I ssl the admin area on my current site running marketpress, the "Add to Cart" button doesn't work. This is the error I'm getting...
