Hi I am trying to set up Authorize.net (AIM). I have contacted Authorize.net and all they do is tell me to contact Zen Cart for Support. I have done all the set up correctly as far as I can tell. I try to run a test purchase using several test numbers including a real one and they all fail with:

The credit card number starting with 4222 was not entered correctly, or we do not accept that kind of card. Please try again or use another credit card.

Does any one know how to set this up or what the problem may be. All Authorize.net did in any form of help was ask what the failure code was. Of course I asked where is the failure code and they had no clue. I have the debugging mode set to on with Log and Email selected but I get no emails nor do I know where any log is.
