Wp Flickr Embed gets stuck on 'loading'

I have Wp Flickr Embed installed on this site: http://cathyflorence.com

It was working wonderfully, then for some reason recently whenever I try to use it, it gets stuck on the ‘loading’ like in this picture here:

I also have it installed on this site: http://sevenfarmgirlsisters.com and it works just fine.

Can anyone help me troubleshoot this? 🙂 Thanks!
