I recently downloaded an aircraft package which included the textures, panel and sounds, however I cannot seem to get the sounds to work properly. When I fet the sounds to work, the system CTD's when I select some of the buttom or switches and I get the following message:
Creation failed - check if sound file is available.

The download is: WSP.SGAMD83.28Liveries.zip for FS2004. I followed the install instructions and retried several times. I've had to edit cfg files in the past so I know a little about that, but this one puzzles me. Any assistance is appreciated.
