Unable to open a jar file.

[triskal]

I'm trying to run a .jar file that is a game. It's called moparscape.jar. I double clicked on it, and it says it can't be launched, and to check the console.

So I boot up the console, and here's what comes up.

I don't really know what this means, but i did google some things to open jar files. I tried java -jar MoparScape.jar, and it says it's unable to access. I also tried doing the whole path, and this is what I get.

Did that, then a file called META-INF appeared. I then clicked on the file again, and it didn't work. Error:
