I'm trying to get this stupid thing to work but I'm not quite sure what to do. Okay I turn the POD on and the screen on it reads: "P" and it flashes that multiple times. After a while, it flashes: "POD 2.0", but now it just keeps on flashing that and it won't actually work. I thought that it may need to warm up or something... but it's been doing it for like half an hour. Anyone have any ideas? Thanks.
