If after you click OK on the Windload Calculator, you get an error dialog appear - the problem is caused because Microsoft Direct-X has not been installed on your computer. Direct-X is required by ShedTech to render the 3D graphics.
There is a shortcut to installing Direct-X in the ShedTech Programs Group under the Windows Start menu. If you do not have the shortcut, you can install Direct-X from the installation media you initially received containing ShedTech. The Direct-X installation routine is only supplied on the initial setup media and is not included in any updates that you receive online.
You must exit ShedTech and restart it again after installing Direct-X for the change to take effect.
