All fixed. I just needed to remove every trace of the Creative drivers and software, reboot and reinstall everything. Not too bad to fix but at the end of the day it shouldn't need fixing in the first place.
Well that is good. At least it's not rendered obsolete like what happened to the Auzentech X-Fi Prelude. The only way it'll work is to disable driver signing but then you're no longer taking advantage of security features.
