I will contact them asap, but I get the feeling that they're going to say that they can't actually help with this issue and to contact Avid.

I haven't been able to find many other issues like mine, but those who have had the problem found that when they registered there product, an authorization code was emailed to them. When I registered my product 2 emails where sent to me, 1 confirming the details of my registration and another one that gave me the authorization code for my 3rd party content, but still no authorization code for PT 8.0.4. I just don't understand why an authorization code that is included in what you buy, comes up with an invalid error.
