Rovio Commander is available again. I have added a new protection scheme. Rovio Commander still uses your Rovio's MAC along with a conformation code. This conformation code scheme also checks in the code and if there are two or more Rovio's on different newtork your code will be disabled. DO NOT share your CODE, if your code is shared then it will become invalid and you will need to purchase another code.
Thanks for everyones support.
