Help~Testing my Checkout with Authorize.net(AIM) and keep getting declined.

[kdpz]

I am finally testing the webite with Authorize.net (AIM) I first used all the test numbers they gave me and they all worked fine. So I took both zencart and Authorize.net out of testing mode and tried testing with my own credit card. I went to submit the order and got a credit card decline error that took me back to the billing page. I tought ok baybe it is my street address an an abbreviated word. I checked my cc statement and just updated the following

W. to W
Road to Rd.

and tried processing again and still got the same error.

Does anyone have any idea what the problem is?

What version of Zen Cart?
If you turn on Debug Logging in your ZC AIM module, what information appears in the log when you get the decline message?
