RSS feed issues with AutoBlogger

We are looking for a way to add real estate home listings to this website and most real estate companies are protecting their listing feeds. So we found this link to generate feeds per city: http://www.trulia.com/tools/rss/#code_block and created one for http://www.trulia.com/rss2/for_sale/Cedar_Rapids,IA/
I cannot get Autoblog to recognize the blog feed?

I've enabled these addons: https://www.evernote.com/l/AAcZsvgQF85NipUd1qUlzdXnbAVeq6GOj0QB/image.png
And get these errors: https://www.evernote.com/l/AAdF3A_lpuhDKrzdBfBvNOCZsQQWAHX9ILUB/image.png

Any ideas/suggestions are appreciated!
