Hello. I was invited to the Preview Program by one of my friends on Live. I received the message on my Xbox One to invite me to the preview program from Microsoft and the message disappeared. I can't seem to find it anywhere to be able to get the link to set it up and download the app. I tried going to the http://forums.xbox.com/xbox_early_access/update_preview/registration_support/default.aspx link but it says Group Not Found. Is there anything that can be done to resend me the message so that I can enter in? Thanks for your help.
