Need help with LEDBlinky

[jtb1987]

Hi all,
I've finally gotten around to attempting to install LEDBlinky on my cabinet but have gotten stuck.
I'm using the I-PAC Ultimate I/O with Launchbox/groovymame.
In LEDBlinky, I've seemingly gotten it setup correctly, but here is what is happening:

When cycling through my Arcade games in Launchbox, I'm seeing the applicable buttons light up dynamically as I highlight a game. When I enter into the game, it goes through the process of reading out the button controls and highlighting the applicable buttons; however, once it's done, it stops highlighting the applicable buttons altogether!

I was able to find this support thread on the Launchbox forums, but am unsure of what the solution is after reading all through the posts:

Thank you for any help!
