I reported this at some point on the beta forum, it's still happening. I had done a track in beta 18, burnt it on a CD as a backup and if I click on the als directly to open live and the track, first it says there's a file missing (that's not in the set, never has been ) and then I get a hangup of live, and need to reboot.
If I launch live first and load the song afterwards, no problem.
