Unsuccessful export from trial version of CS6 InDesign to EPUB

I'm  hoping it's because I have a trial version of InDesign. When I export from InDesign to EPUB 2.0.1

I'm following instructions from this video, but all I get is an empty file. No error message, just the blank file.

I'm trying to test how anchors work for layout in an ebook.

Is it because it is the trial version? I'm hoping so, but if not, any thoughts on what am I missing?

Thanks in advance,

Joan
