Couldn't get any posts. (error)

[lvecsey]

With one private group, I was able to scrape the posts (there are only 3 or 4 in the group) however in a larger private group with more activity where I am also an admin, I get an error of Couldn't get any posts.

Could it be a facebook group setting that differs between the group that works and the one that doesn't? I know the smaller group was recently created, and basically has the default facebook settings. Also I ran this again and outputted some of the html to a file, and now it is titled "Security Check". So I think it is presenting a captcha now.
