Every single time I try to get forge working with minecraft I always end up with the same error. I am following the install guide 100% and yet the same thing happens.

And I have no other mods installed, This is a fresh install of minecraft.

You need to post the log here

forgot that, i'll get it right now

Did you read this:SEVERE] [ForgeModLoader] This version of FML is built for Minecraft 1.4.7, we have detected Minecraft 1.4.6 in your minecraft jar file

2013-01-05 14:54:46  [sTDOUT] A CRITICAL PROBLEM OCCURED INITIALIZING MINECRAFT - LIKELY YOU HAVE AN INCORRECT VERSION FOR THIS FML? download the minecraft 1.4.7 pre-release from http://www.mojang.com/2012/12/minecraft-1-4-7-pre-release/ or downgrade forge.

And did you paid for MC? This could be the problem.

I had the same problem and now i use the magic launcher.

I have the paid for minecraft version. The problem is the download link on the site that says 1.4.6 is the 1.4.7 version of forge. I think that may be the reason.
