iTunes Error

I've been having some problems with purchased music on iTunes since the upgrade to 7.0.1. Well today I got a call from the iTunes tech support team who informed me that I can't authorise my laptop until I get my broken logic board fixed. Apparently when you authorize your computer it looks for some hardware information that my dodgy MBP can't provide so the authorisation fails with this error:


Hopefully this will provide some help to other people with this problem because I certainly couldn't find any mention of hardware problems causing ITMS specific errors.
