Never ran into this problem before.. this is my first custom in almost six months.. so maybe something changed. I don't know. However, when I try to start riff repeater on my newest custom (Blitzkrieg by Metallica). It hangs, then it said I miss zero notes.. then it restarts, hangs again.. then says I missed zero notes... rinse and repeat. Also if you exit riff repeater without actually STARTING riff repeater.. it will hang, then boot you back to song selection screen. anyone fix this issue before or know what is wrong?
