Hi there,
>Mac or Windows? OS version?
Windows7 64bit
>Was the last save a normal Save or was it a Save As over the original file?
Normal "Save"
>Where was the file stored? Internal hard drive? External drive? Network volume? Other?
Internal hard drive
>Was the file in a cloud synchronized folder (i.e. Creative Cloud Files folder, Dropbox folder, etc.)?
It is possible that it was at that time in a Dropbox folder.
Files will be mailed!
Would be nice to include some sort of autosave (to generally minimize possible dataloss) and something to package muse projects. Packaging Muse projects (just collect all used files to a folder together with the project file, relinking all elements) would allow it, to backup projects that use network volumes.
Thanks again.
regards,
