T-Rudder Mk. IV Not detected

[TIEZINE]

I have a nearly new (ebay purchased) set. 2 GF2 bases, 1L 1R Kosmosima grips, TM HOTAS Warthog and a Mk. IV T-Rudder.
The sticks Throttle and config software work perfectly.
However, I cannot get even windows to see the Mk. IV Rudder, much less the T-Link program or the configurator.
While I may have made an error somewhere. I have tested different Cat5 cables (I have a ridiculous amt of them). Plugged the throttle into both black boxes... They always have green lights for the input, but the rudder never shows up. I would love to get these to work.. I will need your help though. I've run through making sure all the software versions match properly also.. still no dice. Can send screens of anything your team requires.
Thanks!! PLEASE HELP!

Plug the rudders into one of the Black Boxes together with one of the grips. Hit the Start Calibr. button and calibrate pitch, roll, twist, ministick and rudders. Hit End Calibr. and check the Test tab, then Axes - the rudders should be moving on Z axis.
