Recently I updated my virus/ad software and it works with my e-mail so it re-spammed and it deleted the closed beta invite permanently. Is there anyway to resend me the key invite since I was already eligible or is it unobtainable at this point and I'm S.O.O.L. plz let me know. Thanks!

Had you already clicked on "Sign-Up" in the email before it was deleted? If so, the email was no longer required and is OK to delete. If you make it into the 360 Test you'll receive a second email with further details.
