So if I am to understand this correctly, that beta key is just to put me on the list with everyone who submitted their email for a key a while back.
I have basically entered a beta code to be put on a list for a different beta code.

I also got a code/key on a poster. I entered it at shootmania.com/beta, and it just says they will send me a key when the beta starts. I thought it already had.
