Dennis,

What have you done to my baby? Well, that's the first time I've seen that one.

OK, a workaround 'cos I've no idea what the problem is.

In the scripts folder, in the options.ini set the voices, SFX and music all to false. Sound will be disabled in the game and it won't look for that file.

I've no idea what caused it, 'cos as you say - it's there.

Thanks for looking anyway. Once you've done the workaround, let me know what you think please...
