Batch Pano for Mac Problem(7.30.6282

I have downloaded Panoweaver Batch for Mac and trying to demo it to see if it will improve my workflow but after stitching is complete all I get are black panos with just your logo on, no previews.

Stitching at 6000 x 3000.

Tried viewing in html 5 and flash and both black with just logo on all images.

Any ideas?

Update: I have just tried the software with the sample images included and all worked fine so a bit strange. The images I am trying to stitch are from a canon 60D.
