Something's not working. It looks like the API call to GoToWebinar isn't succeeding. This may be because you are on a trial account. Unfortunately API calls can't be made to GoToWebinar accounts on a trial. If you do have a full GoToWebinar licence please try re-authenticating the plugin again by pressing the 'Click here to get Auth and Key' button in the plugin settings. You should also clear the cache or turn the cache off in the plugin settings and this should resolve the issue.
