A while back I converted a file over to .mobi format, and it loads and views with no problems on the Kindle, but can not be viewed on Calibre.

When I try to view it the view window opens, the progress 'spinner' goes. After a few minutes the spinner starts to slow, still no document being viewed. Eventually the spinner stops (~5 minutes), and thats it. The document still has not come up. It's not a big issue for me, since it does fine on the Kindle, but something is amis that it will not display on Calibre.

Thanks....... Henri
This is the error report that finally came out after 15 minutes:
