Dumb and Dumber

SO I always mix my tracks and then once I bounce down to a stereo track. I delete the rest and rename the new project (songtitle)mix. Last song I did Sonar had a blip and closed before I could do this and I lost all my song tracks. Autosave has the same mix track. Is there anyway/where I can recover the tracks for this project?

thanks in advance

Thanks John,

I usually save all my work then delete them just so I can resave a a mixdown track, just did'nt get it this time.
