Crash worlds, when i play minecraft with Forge

[Lololoshka]

Good evening! I have one problem with Minecraft Forge. It works only at version 1.6.2 . When i try to create world with new versions of minecraft and forge, this world crashes. Here is my crash: http://pastebin.com/cE5XtZiT. I deleted Minecraft and Java   

and tried download it again, but it doesn't work. Please, help, i don't know what to do :'(

Add -Djava.net.preferIPv4Stack=true to your JVM arguments in the launcher. We set this by default but for some reason your computer seems to not detect it.
