Minecraft keeps crashing.

My Minecraft keeps crashing. This started happening when I installed a mod but I installed lots of mods so I don't know which mod. I'm pretty sure FML and Forge is up to date to 1.4.7 and I'm pretty sure all other mods are also.

You updated your icbm but forgot to remove the older version.

Remind me to ask cpw to include such cases in the duplicate mods check.

Ok thanks I fixed it.
