I installed the patch files but still have the same problem.

1. I have had complaints since I began taking orders last Friday (3/16).
2. My test transactions went through fine both with PayPal account and credit card payment.
3. Yes, I have had several successful transactions.
4. I emailed Paypal and have not heard back from them yet.

I just switched to this format last week, before that I was using another shopping cart system and host, using PayPal for payments and have never had this problem. The people that are experiencing this are return customers and did not have this problem with the previous shopping cart.
