Ok, first of all, the reason I'm using this version and not the latest is because is the version RLCraft servers run on, and I'm trying to start one. So I download the win-installer from the website, open it aaaaaand nothing happens. I reinstall java, nothing. I run it with command prompt using this command (yes, I renamed the file to forge.jar for easier typing):

java -Xmx2G -jar forge.jar

and it gives me this error:

java.net.preferIPv4Stack=true
