okay, I didn't have the data storage enabled but I was able to run a successful visa and mc transation. when I ran discover, it said the number was not a valid number....but that is the number given in the module set-up!

when I tried to run a failed transaction, it said " We apologize for the inconvenience, but we are presently unable to contact the Credit Card company for authorization. Please contact the Store Owner for payment alternatives."

the message I got when ran my own card was an actual "decline" message.
