Yey I'm so excited! This morning I finally found out what was wrong with my launcher so now I can play Voltz. I had thought it was my computer but its not. The download is missing four files and no one has bothered fixing this problem. Oh well I found this all out at the link below. Happy nights till next time everyone. Im off to try out voltz.
