As luck would have it, my Windows XP PC blew up. I managed to source a Windows 7 PC with a parallel port, install mach3 and transfer over my config XML and license from an old backup. Doing this seems to have transferred over the pin settings etc, but I can't get any movement out of the motors. The DRO is changing like the machine is moving when I use the arrow keys, but the motors aren't working and the spindle won't start up with the usual command either.

I'm using a Marchant Dice (I know) machine with a Tonman Superbox control box. The box's red e-stop LED won't turn off either, which is probably telling of some kind of issue, but I'm stumped after scratching my head over this for the better part of 8 hours.
