I just updated Kontakt because Tonehammer's Emotional Piano and Ambius required a later Kontakt version. Since that update Stylus RMX has started crashing Sonar.
For some reason it seems more likely to crash if I have one of the new libraries from Tonehammer running in Kontakt. If I have one of those libraries loaded Stylus RMX will crash Sonar if I insert that VST.
RMX is also acting strange even if not crashing Sonar, I can't audition loops for example - I get no sound.
Is it possible that the latest Kontakt 4 version is causing the problems? I really had no problems at all with crashes before I updated Kontakt this weekend. Can I go back to an earlier Kontakt 4 version in some way?
