[Plugin: Facebook Comments Importer] Cannot find a post linked to this blog

I so loved this plugin when I first installed it. But for some reason it has started giving me an error code:

“Error: Cannot find a post linked to this blog on the last 10 posts of the Facebook wall. Check that at least one post on your wall links to a post of your blog. “

I’ve tried deactivating and reactivating all my other plugins. I’ve deleted and reinstalled this plugin. Nothing seems to work.

I am using it for a personal page, but it worked great until recently.
Can you help?
