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?

Logs or locking thread.

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

"This version of FML is built for Minecraft 1.4.7, we have detected Minecraft 1.4.6 in your minecraft jar file"

Use 489 for 1.4.6 or update to the pre release.

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