Delete the META-INF that comes with forge and see how that works.

Suspected net.minecraft.Launcher error. What launcher are you using?

Don't do that. It's okay if you delete META-INF in the forge zip.

And, ya, Multiverse should have been ported to use the updated google libs that FML uses.

Meet our wiki: http://www.minecraftforge.net/wiki/

And have you read the EAQ?

Ensure that you have installed EVERYTHING in the forge/fml zip into your minecraft.jar.

Better not. This should have been posted in the ClaySoldiers forum.

It's a forge bug, if I'm not wrong. Update to the latest forge for 1.4.4.

Then unfortunately you'll have to wait it out. It works for me. Check your hard disk for errors as well.

In this kind of issue there is no ForgeModLoader-client-0 log. Can you launch WITHOUT forge?

Ya, happened to me before. Try deleting all your MC files and reinstalling minecraft.

LOL Lex... Ya, we need logs.

You could try iChun's Back Tools mod.

How are you adding your items to the creative inventory?

Make sure you have clean jars.

Install guiapi.

You'll want to ask in Modder Support.

Remove mod_GenTest.cfg from your config folder.

Logs?

Google is your friend.

i used MCpatcher so it's unlikely that it missed something like that but i'll take a look. Don't use MCPatcher, for crying out loud. Read EAQ.
