Authorize.net is approving cards, but my store says "There has been an error..."

[Dr Tweak]

This problem started after signing up for a new account with Authorize.net. Orders processed using Paypal go though fine. However, when a customer chooses to pay with a credit card, they get the error "There has been an error processing your credit card. Please try again." But the payment WAS approved by authorize.net, so they usually try again (two or three times sometimes) and then they give up, only to find that their credit card was charged multiple times.

In my email I get the approval from authorize.net but the order doesn't come through from Zencart, and the order never shows up in the admin panel.

Anyone know how I can fix this?

Here is a copy of the debug log from an order I attempted to put through:

Using version 1.3.8a. Any help would be awesome!

Nevermind. I forgot to set the hash value in authorize.net to match the setting in Zen Cart.

Cheers.

YOU NEED TO UPGRADE A.S.A.P!

Seriously.
