Ok, so I'm mixing an album, everythings fine. But as soon as I trim oR create a fade (sessions begin as about 20-24 tracks, one full region per track) I get the -9131 error. My system has not changed, and has worked perfect up til now. The temporary fix is to open one of the new songs (untouched), play it back, then save it close, and go back to the other song. But I still can't creat fades or edits, which I need to do. Can someone help? BTW, this is on a LaCie d2 250 GB
