Can't add recipes from my blog

Hi
I'm hoping someone can help. I've been using CES for a while and my blog posts have been happily picked up by CES and added to my recipes here on the site. Recently this has all changed and i don't know why....
Anyone else having this problem?
I use wordpress and recently changed my theme -- but it's really nothing crazy different from the last theme I used.
I also started using Windsor Live Writer (have you tried this!! OMG does it every make writing easier) and I'm wondering if that has anything to do with it.

Regardless - even when I go to add a new recipe from my blog manually - CES says it can't find a recipe at that URL.

What am I doing wrong? Help please!

Thanks
