Minimum order module

I have installed the minimum order module and have two questions. Having uploaded the module it now prevents anyone from proceeding to checkout while the total is less then the set 1.50 however the shopping cart page is now blank. Nothing shows no message list of cart items of buttons to remove or edit. How do I fix this to show the shopping cart again and a message indicating that there is a minimum order requirement of such and such to proceed to checkout???

The other questions about free download products. Since the majority of the site is virtual products having a minimum order module is preventing free products from proceeding to checkout, is there any way to exempt the freebie from the module settings????

Ive gotten this far on my own and really need some assistance with the rest. Thanks!
