I have recently changed the computer (Windows 7) on my milling machine and now Mach3 has stopped working. It was working well before on the old computer, which sadly stopped booting up.
The Output 0 does not light up now on the CS Labs CSMIO/IP-M motion controller and the Enable1 light on the Mach3 diagnostics screen is now on.
The diagnostics window for the CSMIO plugin shows that the controller is connected to the computer, all the Inputs are on, but the digital Output 0 is not lit.

I am fairly new to Mach3 and would be very grateful for any suggestions on what may have caused this problem.
