I get this error message when I try to activate my copy of Maya 2013(student edition). Does having gotten it from the Facebook page for Autodesk Education have anything to do with this? I had to use the FB page since the Education Community login is broken(it keeps taking me back to the blank login form even though I know I'm getting the login right.
Both Facebook and the Education Community utilize the same database / serial number generation system, so that would not be the cause. One possibility is that there is an account issue preventing the license from fully syncing, however I just accessed your account and confirmed that the serial number is setup correctly.
As such, can you either try again or send me a Private Message (click on my philip.s profile name and then "Send this user a private message") with the serial number and product key that you're using?
