The preview pane also didn’t look anything like my blog, obviously the style sheet reference was missing. Graphics and content appeared, just no styling.

I fired up ol-procmon to find out where an earth wlw was downloading the templates too.

\Users\[user name]\AppData\Roaming
	\Windows Live Writer\blogtemplates

		\Guid (Each blog ?) *1
			\Guid 1  (For edit)
			\Guid 2  (For preview)

^{This is on Vista and Windows Server 2008, I imagine it’s different on other OS’s.}

*1In this folder you will find 2 index[*].htm files which represent your edit and preview panes. Once I found these html files it turns out wlw had download the k2 css file ‘core.css.php’ as ‘core.css.css’. Renaming fixed my problem, yay!
