Trying to Locate the Cause of the Crackles (Plug-In)

Hi Folks--
 
I'm finally back to recording after moving all of my software and hardware of from Win XP 32-bit to Win 7 64-bit and Sonar 64-bit --mid-project to boot!
 
Now I've just got one annoying problem that I'm trying to figure out. When I playback the MIDI track with the drums from NI Abbey Road Modern Drummer via NI's kontakt 5 player, I get crackle. If I play the Modern Drummer in stand-alone, no crackles. If I freeze the MIDI track from within Sonar, no crackles.
 
I'm checking with all of the my hardware techs, and of course NI forums (nowhere near as helpful as CW forums BTW) and so here I am, trying to cover all the bases. I've tried the memory slider in kontakt 5 player and it doesn't help.
 
My workaround is to just record and edit everything with other drum samples in the full version of kontakt 4 (no crackles) and then just copy the finished MIDI track over to the kontakt 5 Modern Drummer track and freeze the track, but that just takes more time.
 
Any ideas?

Are the crackles mitigated at all by increasing buffer sizes? How about if you purge samples in Kontakt to reduce its memory footprint?

Thanks. Yes, I adjusted the memory buffer and unloaded unused samples out of kontakt. No adjustments I've tried in kontakt have helped.

We can start with the knowledge that "crackles", "clicks", "pops" and "glitches" are all caused by one thing: an interruption in the data stream due to the CPU not being able to fill or empty a buffer fast enough. From there, it's a simple - ha! - matter of isolating which process (or processes) is monopolizing the CPU. It may in fact have nothing to do with the K5 player or the library, but rather some other instrument or effect. Do the crackles change at all when you hit the Global Bypass option?

Wow, u da man. Sure enough, not only do the crackles go away but I get more samples in the play back. I guess it's just a process of elimination until I find the offending effect(s).
 
Thanks--and sorry to get back so late. Life kept asking me to take care of things.
