I am so stuck its not even funny

Hi,

I'm working on this karaoke machine, and all of a sudden, my code stopped working. I have no idea how to post my code, because it's in about 5 files. I deleted some file...stupidly....called SongBook$1.class. The weird thing is, my machine still runs the add, play, and quit options, but when I get to choose, It wont let me choose an artist, it says like 400 cannot read "main" thread or something. Please Help!! ;(

Hey Gabriel,

Did you try restarting the challenge? It seems you deleted a file needed for running the code, since the main() method is missing.
