I just tried doing a fresh install of minecraft and then used forge 920, but I'm still getting an error. I made a new world which crashed, but i was able to load it using the default minecraft. What should I try next?

Here's the full log I did recently update my dokucraft, so I'll see if i can download the previous version to see if it works.

I've been having some issues recently where minecraft crashes on loading a world. This doesn't happen on the default profile, only when I use forge. I know it's not a mod causing the crash since I emptied my resourcepacks and mods folder. When it loads a world, it flashes to the title screen and then just crashes, sometimes pausing on a black screen for a few seconds.
