Lost live set on crash, but got it back

[silicon1138]

I just lost a whole performance using the beta 5.2b6. I'd just finished laying it down in session to the arrange page and was about to save it, but it crashed. Each successive attempt to load the unsaved newer version from cache just wouldn't work. I thought all was lost, but then i opened the original pre arranged version in 5.02 to see if that would grab the cached unsaved performance, but no.
However, next time i tried to launch 5.2b6. it all loaded fine - Phew!
