XF 1.5 HELP! Admin area totally wiped after add-on

I did try $config['enableListeners'] = false; and noticed that my other addons did get disabled, but it had no effect on accessing my admin area.
Big thanks to M@rc for helping me out with this. He was able to fix the issue. @Mike, I believe the action he took was your suggestion which was to rebuild the master data.

Off to make backups :D
