Can anyone explain why this is happening and what I can do to get my Minecraft to run correctly with Forge? I never had any problems with the old way of adding mods, and this new method is giving me hassles at every turn.

Log:http://pastebin.com/9TDtxGnC

It works when no mods are installed, but when I add one mod to the mods folder, it crashes.

Just take all of the mods out and load Minecraft Forge
And then Quit the game.
After that put the mods back in load Minecraft Forge again and
it will work! ☺

are you sure that mod is compatible with that version of forge? i mean, if you put a 1.7 mod in the mods folder and launch 1.6 forge, duh, it will crash. but before you click "play", then above the "log out" button, it should say what versions of mods that forge is compatible with. (ex: it says for me: ready to play 1.7.2-1.7.10 Forge)
