Playback Instrument Track

Hi,
currently I'm fighting with a problem I cant find the reason:
When I record an instrumenttrack with the kontak4 plugin (Abbey Road 60s drums), I can play & hear the during the recording process, but never in plaback mode!? But it works with all other intruments perfectly! What could I make wrong? - I cant find the problem! The written Midi-Track will not be played from the plugin...

thx - regards - Tom (AUT)

-seems that noone in this world ever hat this problem...-
The last Update from Native Instruments solved that - Abbey-Road-Drums are working now!
