Controller Mapping not Registering

[PixelJunkie]

I've rebuilt my PC, which had Launchbox on it (12.16) and ported it over to my new PC. I also changed wheels from a Logitch G923 to a Thrustmaster T300RS. As a result, I needed to update the button mappings in Launchbox and BigBox. When I go to Tools-> Options -> Controllers... Launchbox sees my Thrustmaster, but when I try to actually map/remap buttons, it doesn't register the presses. This is the same thing in BigBox. 

I was able to find the XML in InputBindings.xml and manually change the buttons, and this appears to work fine in BigBox now, but in Launchbox, pressing the 'X' on the wheel moves the focus to the next game, so the mapping appears to be off. In either case, I can't map it via either front end now. But Launchbox is seeing inputs, since my old mappings register presses assuming the Logitech wheel and Thrustmaster inputs were the same (Dpad Up, Down, Left, Right is the same in both).. but when remapping, Launchbox does not recognize it... but when moving around Launchbox / BigBox, Up, Down, Left, Right moves the focus as you would expect.
