Please fix the error and restart.
i tried my old launcher and it didnt open!so im stuck on 1.5.2 voxelmodpack ftb launcher...digiex doesnt work either.

1. Hold down the Windows Key and R to bring up the Run dialog.
2. Type in: %appdata%\.minecraft and click Ok.
3. Delete all files except the saves folder.
4. Try launching Minecraft, and see if it crashes.

I have tried that

1. Download and run my launcher debug tool from here.
2. Copy and paste the error log in a reply post.

See my post here for more information.

From what I've seen so far, that is probably causing the problem.

I posted a solution here, so you don't have to revert your theme to launch Minecraft.
