Have you tried summoning the dark lord? You need to sacrifice a diamond encrusted dragon skull under the light of a full blue moon to do it.

Seriously though, you've given us literally no useful information. Saying you have the "latest" java does not help. Tell us the exact version and bit type of your java. Same thing with your OS. Saying "windows" is not enough. There are like a million different versions of that crappy OS. We need to know which one you have. Also, we need to know what bit type your OS is. Finally, your description of your set up is not useful. Give us some screenshots, or accurate schematics. Just saying "It doesn't work" is not enough.
