sonicx05 Posted October 24, 2014 Share Posted October 24, 2014 I downloaded 64 bit java onto my computer and loaded up normal minecraft with it and It worked fine. when I went to load forge nothing happened. So I deleted minecraft, downloaded it again and downloaded forge (1.6.4) which still never loaded. I went in a file and found this: 2014-10-24 15:28:51 [sEVERE] [ForgeModLoader] Unable to launch java.util.ConcurrentModificationException at java.util.ArrayList$Itr.checkForComodification(Unknown Source) at java.util.ArrayList$Itr.remove(Unknown Source) at net.minecraft.launchwrapper.Launch.launch(Launch.java:114) at net.minecraft.launchwrapper.Launch.main(Launch.java:27) plz help!
