crash recovery

[rda]

after a truly wonderful experience editing a recorded audio session and saving it multiple times, it all crashed when I tried to enter a music track. I assume its a memory problem and I will shift my software to my desktop computer. However, after rebooting the computer and program, I cannot find the edited track anywhere. I still have the original raw track from which I edited (for 12 hours) the final copy, but cannot seem to locate the edited version. How can I recover that edited track and where would I find it? God, I don't want to have to start over.
