empty library

Just put my apple tv on, opened Infuse and my favorites and library have dissapeared! It looked like it had reset itself but when I tried to add my harddrive that is connected to my airport extreem it says there is no content ( but there is!)!
This is the first issue I have had with infuse (pro), love it to bits but now cannot use it at all!

Please help!!!

You may check to ensure you’re entering both a username and password to connect to your AirPort Extreme.

A bit more info on the settings to use can be found at the end of this guide.
