WiseGuy recommends:When a presale code is not found in ticketmaster or livenation - check to make sure that the presale is still valid: you might be looking at a very old post, also remember that there might be more than one presale happening - if there are a few boxes where presale codes can be keyed in you might have to try a couple of combinations to find the winning combination.
