When you install the software you'll be prompted for an email address to send your serial number to. Until your serial arrives you can use the 15 day trial versions of each product. Mine arrived nearly immediately.
Nobody seems to know how long this promotion will last so get yours now from the DivX download page. Instructions for downloading, installing, and requesting/entering your serial number can also be found there.
