You might want to check to see if there is a firmware update. I had all kinds of issues using Vista because of an out of date firmware/bios on my raid controller card. Some software worked, others didn't. I found out what the issue was when I tried to upgrade to windows 7. The OS locked up during install. Only through aggravated research did I find the out of date firmware on the one card. Once it was updated/flashed windows 7 installed without a hiccup and all of those programs that would not work or locked up or just plain misbehaved were all happy once again
