Apollo.'s dashboard

Hi - I have been using your application on Facebook for a number of months now and have gotten a great deal of enjoyment doing so. However, for about the last month when I try to access the Visual Bookshelf application home page on FB I get the same message, which says,

"Sorry, an error has occurred.
We're working on getting this fixed as soon as we can."

Can you help me? I would greatly appreciate it!

Thanks, Patrick.
