Marketpress Order Confirmation Emails Not Formatting


The Order Confirmation emails generated by Marketpress to the Purchaser and to Admin are not formatting at all. The text appears all in one long paragraph. I know this is some sort of a conflict with Paid Memberships Pro, because when I deactivate it, the emails format perfectly but I need PMPro running on the subsite because it's a Members Only site. Is there someplace I can go to manually set the formatting for these Order Confirmation emails, or override the effect that PMPro is having on the formatting of the emails?
