Your page wouldn't come up. But in general, when shooting RAW you should
expose to preserve your highlights right at the limit. When processing
in the PSCS RAW converter, adjust the highlight level with exposure
slider, then bring your midtones back up to where you want them with the
brightness slider and adjust the black with the shadow slider. Don't
expect a RAW to look good right out of the camera.

I, too, couldn't access the page. It tries patience when someone gives
us a url that they haven't tested, then doesn't monitor responses.
Paul has given you good advice. In addition, you need to understand that
digital sensors have limited dynamic range -- the range from lightest to
darkest that the sensor can register.
You might try shooting in center-weighted averaging rather than program
metering. Also try automatic bracketing when the light has much contrast.
Finally, always expand your histogram to see if your image improves.
