Hydravision is ATI's multi-monitor management application, not drivers.
You need to install the latest Catalysts (which are the actual drivers).
However, I can't post a direct link unless you at least tell us what your Windows OS is.
You could also click "save all information" in dxdiag, and attach the dxdiag.txt log to a post in here (attachment feature availabale via the Post A Reply button).
Other than that, I'll leave Mojomaster to provide the support for his plugin...
Ick! It's a WildTangent plugin! I thought they were banned?
