Hi,

I've attempted to add the TopSongs parser and Core Data files into my application, and it now builds succesfully, with no errors or warning messages. However, as soon as the app loads, it crashes, giving the following reason:

  *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'executeFetchRequest:error: A fetch request must have an entity.'

I have renamed all files, including the .xcdatamodel file. Could this be the problem (the renaming of the .xcdatamodel)? I'm assuming this error means that no data can be found.

Thanks.
