Today all my settings suddently reset for no reason and I get this error.

Message: ..\AddOns\LUI\LUI.lua line 6568:
attempt to index global 'FX_Cooldown' (a nil value)
Debug:
[C]: ?
LUI\LUI.lua:6568:
LUI\LUI.lua:6566

I'm obviously using LUI including FX which it's bundled with. Anybody has an idea what the issue is?
