My computer doesn't 'run' jar files, so i attempted to extract it. Within the jar files there was no way to actually activate the game (There was no 'application' file). And if i try to directly download the whole windows version folder from the browser it wont let me unzip it. It states, Unknown Header:0 when i try to unzip it. I happen to be able to use the public version, and it downloads perfectly fine and runs.
