No Waveform Redraw After CTD Recovery

Hi
So I was working on something last night that crashed (CTD) on me. Rebooted Sonar and opened the recovery file.

None of the waveforms were visible. The audio was there, but the waveforms - they were gone (Probably those nasty guys at communist martyr high).

If I am mixing, this really presents no problem. However, I wanted to tighten the bass part using audio snap.

Well, maybe I am just old, but placing markers in a waveform that is invisible is hard for me.

How do I get these back? Are Jughead and I going to have to sneak into the Communist Martyr High Gym and look for the wave forms? Are they still on my machine somewhere? And what about Babs?

Right clicking did nothing for me. Rebooting did nothing for me, though I did have a nice while to contemplate my next move.

Thanks
