3 band analysis wiped all my cue points

I just tried to update my cue points to the new 3 band waveform system. After I'd done a couple, I noticed that the cue points remained, but the beat grids moved. I then closed the program to stop it reanalysing the rest of the songs. When I reopened it, all of my cue points were gone, save for the few that had been analysed to 3 band waveform. If all of my loops and cues have disappeared, I'll be very angry. I spent, literally, weeks of my time setting this stuff up. I'm talking 8 hour days, 7 days a week to sort this stuff out. Please tell me it's not all gone now?
