Ok thats good and it means driver is working fine.
Test with a meter at the port like I mentioned and see if you get the voltage. You can also test the Step pin to Gnd with the voltmeter, depending on the active low setting you will either see 5v and go slightly lower as you jog or 0v and maybe 200mV (depends on frequency) as you jog.  If you are seeing that then test at the far end of the cable.

can you be more specific? Dir + or -? And not sure what you mean by step pin. I am trying to follow but remember I am new at this. If you can be more specific I can follow and do everything you ask.

Ok on your parallel port you have a pin which is set up in Mach for the Dir pin of each axis. I cant remember what it is but if you look in Ports and Pins Motor Setup you will see which one you have set for each axis. Remove the cable from the port and put the voltmeter between the Dir pin for X and the other lead of the meter to a Gnd pin (18 to 25) or the metal case of the port. Next jog X one way then back. Do the same for all axis but obviously changing the lead on the meter to the appropriate pin. Step is just the same except it is the step pin which you have set in Mach for each axis that you need to test.
If you still are not sure I will try and explain a bit better, often I dont explain things very well  :(

I'm so lost....On the ports and pins, X is set to step 2, dir 3 and I'm not sure how that corresponds with the cable and cable pins.

Before we go any farther, is the BOB numbers corresponding to pin numbers?

The Dir pin is 3 and that is the pin on the port that you need to connect to.
Heres a pic out of the manual showing the port on the back of your computer with the pin numbers.

ok, hold tight, I have to change the pin numbers in Mach to match the pins on the BOB.
