one of them things that pops up,all was fine the last time i tracked,today im getting no signal to my Ntrack effex,is it a setting in my emu patchmix that i changed somehow?? 
did you hit the fx mute button and ferget?
Ive had similar problems with the effects not working when selected (ie no VU meters moving) or when they show they are working selecting different effect options makes no difference to the sound in the headphones. Weird.
cant tell what my trouble was,but what i did was too load up that build of n track again and all was cool after
