MediaShield Doesn't Show up in Nvidia Control Panel

Help... I have a xFx 680sli mobo running vista 32. I have configured a 150gb drive with my os and through the bios and raid-bios configured 2x500's in a raid 1. I have also initialized them within vista. Everything works fine and they show up. My problem is that I would like to run MediaShield and it does not seem to install. I ran the nforce driver install before setting up the raid initially. Thinking that it would not install unless a raid was inabled... I have since re-installed the nforce drivers, but still no "storage" option under the Nvidia control panel. Any ideas? Thanks! Stacy
