'Unable to update' on client

Had to re-download the client today, and now the game won't load.
It comes up with 'updating music' and then 'unable to update music' and I can't get on.
I've tried downloading it yet again after removing the previous download completely but it's still not working.

Have you tried to run the game as administrator? On Windows, right click the CreepTD.exe and chose to run it as Administrator.

This is usually a permission problem.

Thankyou! =)
