well there`s a Problem now: I was invited to the Xbox Preview Program,but i still dont have the Message from Xbox. I´m waiting for now longer than a week. Normally, it should take 2-5 Days. I hope somemone can help me.
Being invited does not guarantee you will be accepted.
As the preview is full at the moment it's unlikely you will get in for a good few months yet.
then, i Need to wait until i get in.
But thanks for the Information
