max 6 maxforlive problem patch works only when open in max

As the title says, I have a patch that wont work in maxforlive 6 unless i press the "open" button to edit it in ableton live. Its a strange problem.

this patch works fine in maxforlive 5 (without having to open the patch)

Anyone have any idea why this might happen? Looking through the patch, I have narrowed it down to where a filename is being created an called.

btw there is an annoying problem when posting on this forum. I just lost my previous post because the captcha form gave an error.
