So, a couple days ago, the new pixelmon 3.1.2 came out. I downloaded the file off of the official website, it took me to adfly and then mediafire, where I downloaded it. It got downloaded, the file is called "Pixelmon-1.7.2-3.1.2-universal.jar" I click it in my downloads file, and then it says the usual "This is from the internet, would you still like to download it." Then it says "The Java JAR file "Pixelmon-1.7.2-3.1.2-universal.jar" could not be launched." Check the Console for possible error messages. And check out the picture for what the console says. "No main manifest attribute"? What do I do in order to download it?
