Thanks for posting in the forums! I'm sorry to hear you are having trouble accessing the Slingbox Directory via SlingPlayer for Android Phone.
After logging in to your account in the application, there should be a connect, settings, and directory option, right on the home screen. Do you not see this when connecting? If you do what happens when you try to press Directory?
If you are still experiencing issues after this, I would recommend uninstalling/reinstalling the application. As long as you're logged in to the same Google Play account you were logged into when you purchased the application, you will not have to pay to reinstall it.
Hope this helps!
