I've Just Recently Purchased An Xbox One. A Month or Two Before The Purchase I Had Received An Invite to The Xbox One Preview Program by A Friend. I Read The Invite but Was Unable to Do Anything with It, So I Had Deleted It. Turns Out I've Just Bought An Xbox One and I'm Unable to Recieve Another Invite from Any Friends Who are Already Taking Part in The Preview Program. I Am Seeking Help with My Issue.
