Phoenix doesn't use a registration key to validate its software, it uses a USB dongle, there are cloned dongles available on eBay and even one on hobbyking, but i've had bad luck with the one I tried, "stealing" software is frowned upon by many people and every flight forum i've stumbled on everyone gets bent out of shape when people bring up how to get phoenix for "free" so if we could keep this thread on track that would be great.
