Forge 1.10.2-12.18.3.2511 won't install

[ytarow]

Hello, I have a little problem installing Forge 1.10.2 .

I had to delete and reinstall entirely my Minecraft directory and launcher because the launcher wouldn't work anymore too, but now that it works, I wanted to play my modpack but Forge wouldn't install.

Here's the installing log that Forge made:

Exception in thread "main" 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.MirrorData.<init>(MirrorData.java:63)
	at net.minecraftforge.installer.MirrorData.<clinit>(MirrorData.java:17)
	... 6 more

And if that can help, here are my java args: 

-Xmx3500M -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M

I don't know what to do, there doesn't seem to be anything related to that on Google, so it would mean the world if someone could help me.

Thanks in advance!
