You should receive your licenses along with the KOP in January.
If you are a college student looking to get to know Inventor, but not pay for it, check out
http://students.autodesk.com. You can register using your college email and get an educational license of almost any piece of Autodesk Software. I know at least Inventor 10 and 11 are on it, as well as AutoCAD. Keep in mind however, that this will imprint an educational watermark on anything you do that cannot be removed, so it isn't suitable to use for the inventor award, only for learning purposes.
