I lost my Live Set :(

[StefanoMDj]

Hy guys, i was messing around in Live, and try to load a Set from the Live's Menu, i unfold it to see the various tracks and i try to load it, ableton stops for few seconds and then when it restart to work the live set was gone!
It wasn't in the folder that was previous, it wasn't in the Bin (of windows) it isn't anywhere!
It was a very nice builded live set for live performance, i've build it in 1 week and now it's gone >_>
Anyone knows a way to find it?

backup?

search the entire computer for '*.als'

If it's there, it should be found. * means it will search for all files with the extension .als, which is what Ableton uses for Live Sets.
