I have Microsoft RMS running ON a win7 64 bit machine, and only when you run a American Express card its not printing any credit card slip, or reporting to the system that a sale was made. But when you log into the portal to check and see if the card went threw, it show that the transaction went threw, and charges the customers card. They are processing threw T-gate. Any help would be greatly apprecated
