This is a legitimate license of Oxygen Builder Ultimate Edition that includes auto updates for 1 year.

DISCLAIMER: Oxygen Builder overrides/disables the current WP themes in order to work (so your current theme gets disabled) so your site will look bare until you theme it back using Oxygen Builder. This is normal functionality!
