Song playing back glitchy and slow in Firefox and Chrome

My track is playing back all distorted and slowed down and wobbly (ie pitch/speed is fluctuating) in Google Chrome and Firefox but is fine in Internet Explorer - another user (SteveParker) said he got the same problem when trying to play it in Firefox - I updated my Flashplayers in both Chrome and Firefox to latest and it still happens - should I upload it again? (although it would mean I would lose all the comments). Is it possible for you (moderators) to 're-render/compress' it from the WAV I uploaded? Any help is very much appreciated

here is the track in question:
