Ok the address will likely be fine as thats the normal for an onboard port.
That is one of the backup xmls you are trying to attach, you want to attach the one thats in the main mach3 folder and not in the xmlbackup folder.
You could put a voltmeter between the Dir pin and Gnd of the port and jog that axis, the voltage should change between 5v and 0v as you change directions, you can do that for all axis.
One thing however, have a look on the diagnostics page and see if you get a frequency there, also a time in int. The frequency should be steady and close to what you have the kernel on Ports and Pins main page set to, the Time in int will jump about though, thats normal.
If you dont get these readings then the driver is not working.
