Virb Edit 5.1.0 has broken multi-camera support

Using 2 Virb XE's:

Multi-camera support is now broken. When in picture-in-picture mode, things seem to work correctly. However, in Full Frame mode, if I select Angle 1, the clip in the scrub window updates to show the correct camera, but the preview still shows Angle 2. I can't get the Preview window to display Angle 1. It also seems to remember which clip is assigned to Angle 1 on the initial import because when I removed both clips and reimported them in reverse order, it then wouldn't preview Angle 2 (which was formerly the Angle 1 clip). I tested this with a few other clips and it always affects the first clip that gets brought in as Angle 1.

I exported the video just to see if this was a Preview only issue but the final export was also affected.

Does anyone know if there's a place I can grab the previous version from? At this point, 5.1.0 is unusable for me and I really need to edit video today.
