I'm having the same problem... customer places order and it doesn't show in admin area or database, and I do not receive an order confirmation.

Some order information does show up in the FirstData/Linkpoint CC Review, but not all.

I'm presently using: v1.3.9h
FirstData/Linkpoint/YourPay API Payment Module
Check/Money Order Payment Module
PHP Version 5.2.17
mysql v5.1.56
