Need Help Changing Username from "chimneysweepingseattle" to "albert james" on SongPop2

Hey there SongPop2 community! I seem to have stumbled into a bit of a mix-up. Somehow, my username got set to "chimneysweepingseattle" instead of my intended handle, "albert james." I'm not sure how this happened, but I'm eager to get it sorted out. Does anyone know how I can go about changing my username back to "albert james"? Any help would be greatly appreciated!
