Ableton Forum

I've been working on a mix using ableton live for the past month, and while adding some effects to acapellas I got an error saying something like "critical error occured restart ableton." That was last week, and I haven't touched the mix since then, but opened it up last night to find that all of the waveforms were "grayed out" and live was computing them again before they would play...now all of the blends are out of sync, and the undo menu shows "undo reset warp markers and loops" from the moment i open the file.

is my project completely gone, or what?
