    Everytime i start Max iam getting this ErrorMsg box. Telling me that CoreVideo.dll and CoreAudioToolbox.dll are missing on my computer. I never expierienced this before...
    One result of this is, that jitter wont play video files anymore..
    can anybody give me any advice?
    i installed quicktime again.. but iam still getting this msg..
    thank you very much
