I was working on a particular project last week and all was fine. I worked on others in the meantime and now this morning when I opened the project the main soundtrack (Audio 3) has half disappeared - please see attached.
This is not the first time this has happened. OK, with a bit of work I can replace it but if this is a known phenonmena then for the future I'd like to avoid doing whatever it is I'm doing wrong.
I have the very latest version of PrePro, all files are on an external Caldigit AV Drive with masses of free space and I'm using either an up-to-date iMac or this year's MacBook Pro depending on availability.
Thanks in advance for any guidance etc.
