authorizenet_aim problem with test mode & CC#

We just installed authorizenet aim and are in test mode. None of the test Card numbers work. Here are the numbers we are using.

Testing Info:
Automatic Approval Credit Card Numbers:
Visa#: 4007000000027
MC#: 5424000000000015
Discover#: 6011000000000012
AMEX#: 370000000000002

All come back with this error message
The credit card number starting with 3700 was not entered correctly, or we do not accept that kind of card. Please try again or use another credit card.

This used the Amex card number and when any other card number is used the corresponding first four digits for the card.

Please help...Need this fast

If you don't enable the credit-card-type in your store, then none of your modules will accept it.
