Minecraft can't open saves with the latest version of forge

[supernir]

Hello, lately i wanted to install so mods but i encountered a weird bug.

Minecraft won't create open new save's or load exsiting ones.

I have the log : http://pastebin.com/wy3rukKu

Please help, i have the last version of forge.

Although this problem has been in my minecraft all of this year, just today i bothered to ask help.

P.S My minecraft was ok with mods a year ago.

Thanks

Edit: I already deleted my minecraft and installed it again a few times.

Add this to your VM args in the profile options in the launcher:

-Djava.net.preferIPv4Stack=true
