Thanks for the feedback. I tried your methof kd7eir, but it still wouldn't pick up the driver, it kept ignoring it. Then I found an old thread on here, and someone else had the same problem. What I needed was to download this file and run the application. It then installed the driver.

From here I could select it in Arduino and install the new firmware. This is the first time I've used arduino and connected to the ramps board.

Thanks for the help.
