So I just got Rock Band 2 for Christmas and I was excited to play it. The problem is when I tried to put that batteries into the drum where the middle battery should go there seems to be a missing coil to complete the connection and the battery won't hold it's place. I doubt this is a common thing but is there anything I can do to power the drums before we go back to Best Buy and exchange it later in the week. Also I want to be sure this isn't how it's supposed to be, but i doubt it.
