Missing qualifying license for upgrade

[LilBooker]

Hi,

I'm trying to upgrade from Pro Tools MP9 to Pro Tools 12. As far as I can tell I am eligible to do so. I have an active MP9 license with iLok. The problem is this: when I try to purchase the upgrade from Avid's website and enter my iLok account name, I get this message: "Your chosen iLok account does not have enough qualifying product licenses for upgrade. Please review the following errors and fix them or change your iLok User ID to a different one that contains valid qualifiers for the upgrade.
Missing 1 qualifying license(s) for upgrade to Pro Tools Annual Upgrade Plan (9513-30239-00)."
Any advice on why my valid and seemingly eligible license from MP9 isn't being recognized by the Avid store site?

Thanks...
