Melodyne act weird sometimes in SONAR X2a x64?

Bad audio after rendering back track in SONAR X2a also?
Also Open a saved project and continue editing in Melodyne on a specific Melodyne track give you bad audio, robotic sounding and sometimes. It even sometimes "cut off the audio stream" completely? Anyone else?
