Hi Newbie here,
I have just installed Calibre v4.18.0 on my Windows 8 pc.
I am unable to view either .mobi or .epub files with the Calibre viewer or Editor.
I get a splash screen stating "Preparing to view ebook", which flashes up briefly and then disappears. No error message.

I can convert files .docx to mobi, epub but not view them.
The problem is also occurring with the supplied "Quick Start Guide.epub" so nothing to do with my own book conversions.

Is there a debug log which would give a better clue of what is failing?

Thanks - E
