I've posted this on the Ableton forum as it's probably more of a Live issue, but thought I'd seek help here, too.
Whenever I use files from the Ableton library in my Max For Live devices then save and exit the Live set, they aren't recalled when I re-open - I get a 'media files are missing' message. Files from my own sound library are recalled, however.
I think it might be that the library is 'read only' - I've managed to change individual files so that they aren't read only but whenever I apply that to folders, they revert.
Is there a way around this as it's infuriating! I've taken to making screenshots of my sets so I remember what samples to load into which M4L devices!
