[Blackwidow Elite]

Where can I find the latest Blackwidow Elite drivers? I can't see it in the list here. I am having an issue with the volume wheel on the BlackWidow Elite after a recent windows/dell update. System info: I've updated Razor Cortex/Synapse, but not having much luck. Previously the wheel movement was very precise; now if I move the volume up/down, it makes big jumps, or goes one way and then another. It's very frustrating.
