'Edit Metadata of a Database File in Mac OS X

I need to edit a database file (.fexdb), and in fact I can do so using BBEdit, but upon saving, the application to use that database (FontExplorer) no longer recognizes the file (also the icon has changed). It seems some metadata have been altered by BBEdit (I don’t even know if that is correct—is it?). Would anyone be so kind as to let me know (on a non-coder level) how to proceed?

Thanks!
