ShadeZinc46

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 Exception in thread "main" java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at net.minecraftforge.installer.Java6Gate.main(Java6Gate.java:48) Caused by: java.lang.ExceptionInInitializerError at net.minecraftforge.installer.ClientInstall.getSponsorMessage(ClientInstall.java:401) at net.minecraftforge.installer.InstallerAction.getSponsorMessage(InstallerAction.java:60) at net.minecraftforge.installer.InstallerPanel.updateFilePath(InstallerPanel.java:334) at net.minecraftforge.installer.InstallerPanel.<init>(InstallerPanel.java:315) at net.minecraftforge.installer.SimpleInstaller.launchGui(SimpleInstaller.java:167) at net.minecraftforge.installer.SimpleInstaller.main(SimpleInstaller.java:54) ... 5 more Caused by: java.lang.ArrayIndexOutOfBoundsException: 1 at net.minecraftforge.installer.MirrorData.buildMirrorList(MirrorData.java:84) at net.minecraftforge.installer.MirrorData.<init>(MirrorData.java:63) at net.minecraftforge.installer.MirrorData.<clinit>(MirrorData.java:17) ... 11 more Can anyone help me?
