I have Microsoft RMS installed on a win7 64 bit machine, and I have installed the driver for the pin pad, and it shows that it has connection, due it powering on. But when I try and run a debit card transaction, it giving me a error message, and it's not working. I have tested the pin pad in my office numerous time and it works here, but when I'm at the site it doesn't not work at all. Any help would be greatly appreciated.
