Navi-X suddenly stopped working, crashes on launch

I've been using XBMC nightlies on my atv2 for over a year without any major issues. I updated to the latest nightly last week and updated to Navi-X 3.7.6 and now I can't open Navi-X at all. It just crashes my xbmc and kicks me back to the atv menu. I tried uninstalling and reinstalling navi-x, downgrading to an older version, downgrading my xbmc to an older version, rebooting atv, etc etc.... No luck. I saw someone mention something about disabling air control in the nitoTv menu, but I didn't install anything via nitoTv so I don't have that menu.

Any ideas? Please help
