JP,
Is the spot that appears to be damaged on the outside of the screen or is it behind the screen? If it's outside and just a blemish and not scratched, you may be able to use Plexus or something similar to remove the spot, but before doing anything, call ML customer support, they're really good at helping there customers, or at least from my experience they have been... "D"
P.S. After you get the screen issue resolved, you can buy universal screen protectors at Walmart for just a few bucks and cut them to fit your screen to prevent any further damage, which I thank God I bought some on the advice of a friend and it wasn't a week later that I hit the screen with my Lesche tool and fortunately only the screen protector got scratched. Take care...
