I started Minecraft. Once It finished opening I clicked on my inventory (E). After I clicked "E" Minecraft crashes. What does this mean? Crash Report:

Ah, that was my issue. Thank you very much!

This is the file it tells me to refer to.. But I have absolutely no clue what any of that means.

So I got a new computer and I wanted to return to playing Minecraft with mods again. I came to Minecraft Forge and downloaded the latest version (December 30th). I dragged it into the minecraft.jar and then deleted the META-INF. Then once I try to open Minecraft, this thing pops up while it is trying to load Forge that says, "There was a fatal error starting up minecraft and FML. Minecraft cannot launch in its current configuration. Please consult the file C:\Users\Tyler\Appdata\Roaming\.minecraft\ForgeModLoader-client-0.log for further information." What do I do? Can someone help?
