I've installed 0.9.7 after removing 0.9.6 on my netbook (Windows 7 Starter SP1) and my PC (Windows 10 64-bit 1511) and I got the following error message when I opened an epub to edit the formatting (font size, margins etc).
'
Unsupported XML media-type: application/vnd.adobe-page-template+xml'
I've never seen this error before in any previous version of Sigil I've used.
Below is the HTML code at the beginning of each file. I've only removed the name of the book from the <title> tag.
The book, published earlier this year, is Epub2 and has had its DRM stripped and it hasn't been anywhere near Calibre.
Both the Well-Formed Check Epub or FlightCrew reported No Problems when I ran them.
Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"

<meta content="urn:uuid:de119b4b-b9c3-4241-b43e-f73df2d83856" name="Adept.expected.resource"/>

So far I haven't found any other files with an Adobe template to see if the error is repeated, but I'll keep looking.
