Once I run it to play it in the game, no notes or music plays. What did I do wrong? I'm new to DLC and the tool is terribly confusing for me. 

@@Harrisonb Are you trying to make one or play one?

I'm trying to play one. I do not have the cherub rock dlc but I've got plenty of others, so I used the tool and re packed the song as a Dlc that I own. It shows the preview, album art, and plays preview music. It asks me to tune my guitar, once completed no music plays or notes come across the screen.

Make sure you have the proper dll
