n-tract and kontakt2 vst. My f3 key is silent

Using n-tract and kontakt2 vst. My f3 key on a m-audio radium 49 is silent. Plays fine as a stand alone. Anyone seen this or know the work around?
I tried this vst on SQ01 and it plays fine.
Thanks

Oh, the vst keyboard f3 key plays. must be a midi thing with my midi-controller and n-track.

Ok, silent key is fixed. Downloaded and installed the 1811 new build. But I keep getting midi out and sysex errors. any ideas?

I am using 4.04 new 1811 build with a m-audio firewire 410. I can play all my NI synths and can record but get the above errors when I try to playback.
Please advise.

Thanks
