I also have problems concerning the latest version of ARL from WAU.
It messes up with Omen, Recount, Bagnon and SCT. Even though those addons are shown in my addon list and marked as activated they won't show up ingame and even the slash commands e.g. /omen don't work and just cause a message from wow about using /help for getting more slash commands.
After trying several things I found out that deactivating ARL brought back those other addons to my game.
BTW: I like and already miss your addon :(
