I have the latest version of Java and Minecraft. My computer is connected to the internet, my cache is clear. I have tried literally everything I have found to fix this. Please help. When I launch the installer, this message comes up. Exception in thread "main" java.lang.ExceptionInInitializerError at net.minecraftforge.installer.ClientInstall.getSponsorMessage(ClientInstall.java:326) at net.minecraftforge.installer.InstallerAction.getSponsorMessage(InstallerAction.java:59) at net.minecraftforge.installer.InstallerPanel.updateFilePath(InstallerPanel.java:236) at net.minecraftforge.installer.InstallerPanel.<init>(InstallerPanel.java:217) at net.minecraftforge.installer.SimpleInstaller.launchGui(SimpleInstaller.java:153) at net.minecraftforge.installer.SimpleInstaller.main(SimpleInstaller.java:40) 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) ... 6 more I don't know what to do. When I turn off internet, the installation actually works a bit, but I attached a screenshot of the error message that soon comes up.
