So.....yeah.....

Does anyone know why I don't have any 3D sound options in the Sound Options part of the menu? Here's what happened....

When I installed Windows Vista, everything went fine except that Creative had not released any Vista compatible drivers, and Microsoft didn't have any compatible drivers for the X-Fi Xtreme Music Platinum Soundblaster card, so I was stuck with this basic sound driver that gave me monaural sound. And thus the 3D sound options in D2 didn't work, understandably so. However, Creative finally came out with some new drivers and software, I installed them and sound is working just fine now. However, the 3D sound options in D2 still are not accessible. Is there anything to be done about this? Do I need to un- and re-install D2 or something weird like that?
