As Greg already pointed out check your location options.
The default location in Sketchup is Boulder/CO.

Also Sketchup assumes that your North direction is at the top
of the screen if you're in a plan view (+y if +z is height).

The conversion of Sketchup settings to gensky parameters
works on Macs rather well. On Windows the locations data file
is named differently which I haven't taken care of yet.

You can reduce the QUALITY setting in the .rif file to increase
the speed of the preview image. You can increase the 'ab' setting
separately ('render=' option in the rif file) if the settings
rad would create are too low.
