Could anyone tell me why when I'm trying to import from a fb fan page, from 30 posts User Post Likes, Nodexl imports 30 posts but only few likes. For exemple the page has a post with 540 likes and NodeXL show "0 likes", another post with 17 likes, Nodexl show 0 likes and are many. Otherwise are some posts that are ok but I'm not happy with that.
