Darwinia crashes on startup - Sound Decoder error

[82PercentHam]

When I try to start up Darwinia, I get an error that reads like this:

Fatal Error
Failed to open sounds stream decoder: sounds/world4

The game immediately crashed, and when I tried again, it gave me the same error, only instead of sounds/world4, It said sounds/world1, and then later sounds/world8.

Please help, I would love to get this lovely game running.

Thanks.

EDIT: After a few more tries, I realized that the game is having problems with all kinds of sound files, such as tresk_-weeklies-_shroeders files, matrix, and speccyloader. Please help.

Never mind, a simple re-installation fixed the problem. Thanks for all the help anyways.
