Done Crash

I know this is not your launcher modpack but can someone tell me why am I crashing?

 

That looks like it might be an issue with Optifine...

Are you using Optifine? If so, what version of Optifine are you using?

 

1. Description: Initializing game
2. 
   
3. java.lang.NoSuchFieldError: ofAaLevel
4. at Config.initDisplay(Config.java:196'

Seems like something isnt loading right have u tried reinstalling the pack

What was the last ting you did

 

yup, it was my optifine. I was using 1.10 instead of 1.10.2.
