doesn't work with Flickr Group

I am using the plugin with a Flickr group, but I get the next error message: “Flickr feed was successfully retrieved, but no photos found “. I have pictures available at the group and I tested with several groups with differents groupID, but the erros is always the same. What can be happening…?. The plugin works fine with Flickr User

Thanks
