Authorisation problem upgrading to 9.0.3 error 42408

Question

Since I upgraded my iTunes to 9.0.3, everything I bought before I changed my Apple ID is no longer allowed to play. It asks me for my password, (but with my old apple ID), when I give it, it gives an error 42408!
This is also a problem flagged in the mac forum, but I thought I'd make sure it gets mentioned here in the windows one too.

Answer 1

Just upgraded to 9.0.3 tonight. As others have mentioned - everything was working fine before the upgrade, but afterward, I can only play music I've ripped from my own CD's. This error appears in my Application Event Log:

Tried running it from Program Files, No Go. Tried deauthorizing, then reauthorizing, No Go.
