I tried installing forge but after installing i launched minecraft and it froze at the done loading screen.
I am using 7zip, minecraft version 1.4.2, Forge version 6.0.1
This is a fresh install of minecraft with no mods.
And I followed all the directions (including deleting the Meta-inf)
I down loaded 6.0.1 here http://www.minecraftforge.net/wiki/Main_Page
