Well if you are having problems in both games, it is likely not the audio file format, as we released WW2 with WAV sound files, as some sound card drivers, codecs, and cards cannot handle multiple simultaneous MP3 sound streams.

Have you turned all sound off? (including the mouse click found in the main gane options launcher misc tab). If this lets you play, you have some problem with your sound card or a codec, or the card itself. And since you have upgraded to XP, I would tend to suspect the sound card drivers, since the fact you can get into the main screens seems to clear both DirectX and your video card drivers. But I would still ensure the video card drivers are the latest XP compatible ones, as well as the drivers for your sound card.

Does your system meet the specs for RAM and video card RAM?.
