WiseGuy suggests: If a presale password is not working - check to make sure that the presale is still valid: you could be looking at a very old post, secondly remember that there might be more than one presale happening - if there are multiple boxes where presale passwords can be typed in you might have to try a couple of different combinations to find one that works.
