2 Checkout Plugin, no confirmation email being sent

Hi, I just purchased the 2Checkout Plugin. Everything is working fine except that once the order is completed, no confirmation email is sent to the customer or me. The order status is changed to "confirmed" just no email sent. This is important because the confirmation email contains the link for digital goods.

When I use the Paypal plugin, it sends a confirmation email. What can I do to change this?
