Okay okay...so I made an installer that basically installs PRISMNDS.DLL correctly and quickly (and works with the Linksys WCF12). You may have seen me blab about it recently in this forum. It should cure your problems, but I can't make any garuntees. I call it Perfect Prism (because it works perfectly :p) Interested in trying it?
http://prism.tjtech.org. Want me to shut up about it? Just say the word, but so far it's helped others with their problems. Tell me if it works for anyone here by the way, I want to increase my list of working cards.
