[santolina]

Hello.
Im getting this error message when I render a comp in After Effects 6,its not every time but at least 75% of the timewhich is enough to cause problems which are when I laod a sound file (WAV) into the time line and then try to render the scene,the scene will render normally untill it reachs the sound file and then stops and the result is the error message

After Effects error: opening sound component (-2166)

It appears when Im rendering the comp in A Effects as QUICK TIME uncompressed,and even with AVI UNCOMPRESSED

Im working with XP--service pack 3
AMD Quad core

Quick time Pro installed latest version
