Microsoft actually took all the old starter kit codes out of their database - so they don't actually work anymore. Customer support won't be able to find any evidence of the code existing and you'll pretty much not be able to get anything out of it.
I've got two unredeemed cards on my desk at work and there's pretty much nothing I can do to redeem them. Microsoft CS kept telling me to take them back to where I got them (even though I mentioned several times that they were from 2005).
If you somehow manage to redeem the code, let me know how you pull it off.
