build sound problem

I have just built my app and relies on external wav. files for sound.
The problem is after building no sound works ,nothing...
The built exe and the mfa file is in the same dir so it sould find the files.
The mfa file works 100%
Any Ideas?

Make sure you've included the sound filters you need - they're not included automatically when all sounds are external. (They're in the Application Properties.)

Ok thanks it works now.
It seems even if the automatic is checked you still have to uncheck and select.
thanks again.
