When it is activated and you go to "authenticate" it, there is nothing to click to authenticate it, only a link to the German version of their website. all the website says is basically activate then authenticate. but there is no way to authenticate.
I was using the older version and it worked fine, when I updated my plugin it stopped working. I removed authorization and was going to re-authorize (same procedure as was needed to get the twitter-facebook app to work as-per twitter advice) but everything disappeared except the brief description of the plugin and link to website.
