Own ModPack Crashing

[myth494]

Hi, i've updated some mods on my mod pack (about 40 mods, they're all updating) and i now get a crash on launch. i cant seem to find anything obvious in the logs, but i have near no experience in it either. here is my fml-client log: http://pastebin.com/2yZCH4cb

 

and in case it helps, here is the crash report: http://pastebin.com/DDdd6rT4

hi,

The crash comes from this line : https://github.com/MinecraftForge/FML/blob/master/src/main/java/cpw/mods/fml/common/Loader.java#L230

It would seem that a dependency is null.

Try to install the mods one by one until you find which is causing the problem.

ok i managed to find the problem, it was an outdated version of a mod (accidently grabbed the wrong one)

 

thanks for the help
