hotkey bar? you mean the action bar? did you re-assign the keys associated with it?
did you 'spin' it so it's not on the right one?

when you hit '2' on your main... does the '2' action bar light up on wow4?

if you are on wow4 and hit '2'... does the action button light up? does the heartbeat move? does the '2' on your main's action bar light up?

also, please upgrade to v1.8k when you get a chance
