Guitar Rig does not produce monitor sound anymore?

I have a track, monitor sign (yellow) is on, playing guitar live, cannot hear the guitar sound (only the clean one thru my interface).
after recording i do here the guitar sound from my recording.
What´s wrong?
thanks, maz

Do you have direct monitoring enabled? If so, that’s probably why.

See this image:

That knocks out your VST effects too but once you have a dry track decently recorded, switch the direct monitor off and mix away.
