Toshiba netbook showing as counterfeit

[arablizzard2413]

Ok, so I used a key for Windows 7 Professional on my MSDN-AA (or is it called Elms?) account to upgrade my Toshiba netbook to Professional from Starter, I login today and I'm greeted with a message saying I might have a counterfeit copy of Windows. Unless my school is doing some shady business, that can't be the case. What gives?

EDIT: System properties has the blue Genuine logo and it says activated, maybe it was just a fluke then.

AFAIK, Toshiba also requires registration with themselves. Maybe they don't recognise the key you entered when installing Windows?
