Sonar X1 Studio - export MIDI/audio troubles

Hi all,
I have troubles exporting "mixdown" of my tracks. The project consists of both, audio and MIDI. Audio tracks render just fine, but MIDI tracks are about 8th "quicker". By that I mean I have to move them 8th note forward to sync with audio tracks. I have found this by exporting not a mixdown, but individual tracks, imported those into a separate project and there I could see it. However, that is not all, also the automation on audio tracks is "screwed up", it just doesn't sound the same after mixdown/export as when played in the original project file. I suspect I have some wrong settings somewhere in the jungle of Sonar's settings for exporting or latency compensation etc. 
 
So to break it down...
 
1. The original project, played as it is plays perfectly fine
2. When exported into mixed wav, MIDI is moved in time and the automation is skewd
 
Details of what I am using and am aware of...Windows 7 Ultimate 64 bit, Sonar X1d (build534) in 64bit version. Audio card - NI Komplete Audio 6 in ASIO mode. Audio card buffer set to 128 samples, output latency says 7ms, input latency 5ms, total roundtrip 12ms/557 samples. Project uses 44100 sampling rate and 24 bit depth. Not using 64 bit double precision engine as default, but tried using it on export settings, didn't make a difference. Also tried to use "record latency adjustment" setting using the reported latency 557 samples. Didn't make a difference.
 
I am running out of ideas here. I cannot export the project to show and play it outside of Sonar. Oh, and I tried to bounce the MIDI track into a new audio track and mute the MIDI track afterwards and mixdown with just audio. Still the same issue. Strange.
 
I can move the MIDI parts manually, but the skewd automation is silly.

Not really...when I bounce to another track in the same project it plays correctly along the MIDI track, only when I export (you could say bounce to wav, I guess) the synth track audio  (in my case linked midi track and audio output from a synth) into a mixed wav (which later I would convert into MP3). Then in the mixed wav I can hear the track is moved...out of sync...and modulation of one of the audio tracks sounds different when compared to realtime playback in Sonar.
 
Yes, exactly, it should be offline without latency issues from the audio card etc. I have fast bounce checked. I think I tried to do the audible bouncing too, but had issues with it too, but I will double check that right away. 
 
I also thought it might be because this project was started and at one point I needed to reinstall Windows (I know, silly) and after that this project had troubles loading Battery and Kontakt at the point of opening and I had to select the proper path to samples etc. So I just finished a new project where I mirrored all the settings and tracks and everything from the original, but with a freshly opened Battery and Kontakt, so I have no issues in this regard anymore. But that didn't have any influence on export, of course. But I tried.
 
BTW, thank you so much for replying so fast.

Reading your specs I'm not sure I see a audio interface unless it's the Native Instrument device. 
 
I had this exact issue years ago when trying to use a Creative Sound Blaster audio card. So to me the answer is in your audio drivers.

Yes, Native Instruments Komplete Audio 6 is my soundcard. I used to have ESI Audio DuaFire which I have troubles all the time regard to their drivers. That was one thing I bought Komplete AUdio 6, to get rid of ESI thing. I hope it is not drivers. At least I didn't have this trouble since I bought it. I worked on one project before this and had no trouble with exporting in that one. 

Now I noticed another thing, that break sample cannot be changed into groove clip. Other samples used there can. Why is that? I think I am getting closer.....

Cool. I was out for a few days so didn't see your previous updates. If a clip can't be converted to a Groove Clip, that suggests it's already been stretched with Audiosnap or is another type of tempo-matching loop like REX.
