[Plugin: Facebook Comments for WordPress] Comments not pulling from FB

I tried this plugin and added my own XID. It is showing comment box but not pulling any comments from FB. I have used a search app I have developed as an APP ID? Is there any restriction for APP ID or Kind of App I can use ?

Does it takes time to load comments from FB. I have tested for 10-15 mins only.

When I said comment from FB, I have said about my FB page (http://www.facebook.com/satyaweblog). I think the plugin can pull comments from here! or it can just pull comments from my profile?

Thanks
Satya
