I recently installed Dogz 5 on my PC. When the game boots I am given an error indicating the sound will not function. The error message reads as follows: "Sorry: The sound system did not initialize. No sounds will be played. Please select Help for more information." When I checked Help I was told to try reinstalling. I did so and during install asked the game to install DirectX 8.1. This did not work. I also tried to update DirectX at microsoft.com. The update would fail. What's the problem???
