Indexhibit Support

I have just purchased and installed Indexhibit on my local development server. When trying to create a new exhibit I get the error message: filesource class not found

What does it mean and how can I prevent this?
I have searched for this error message in the forum but no results.

I'm sorry, we can't help on local installations because it could be so many possibilities…

But what does the error message mean? All my other development projects incl. several WordpPress sites run perfectly on my server.
