i have ran the winMerge tool, but there are hundereds of files that show up as changed. Most of these have to do with the template and the ez pages, but I do not know what they all are. Is there a certain section that i need to focus on? The only customization that i did was modify the default skin.

Customers have three options to pay: check/moneyorder, PayPal, or CC with Auth.net. Only the ones that choose Auth.net don't send the order email. I get the email from auth.net, but not from the store. From the customer end, nothing is different. Everything goes through fine for them (no blank screen).

My client is getting very frustrated so any help or direction would be greatly appreciated.
