Error with 1.4.2 and Forge

[ChompShadow]

I got an error when loading MC. This is it:

 

MagicLauncher 1.0.0

java.home: C:\Program Files\Java\jre7

java.runtime.name: Java SE Runtime Environment

java.runtime.version: 1.7.0_06-b24

os.name: Windows 7

os.version: 6.1

os.arch: amd64

sun.arch.data.model: 64

Missing class member: public B c, class: agl, mod: Forge.zip

 

Please help me out, thanks.

Have you tried using a different launcher?

[ChompShadow]

No, what other launchers are there?

MultiMC has been known to work.

Screw Magic Launcher. Its error detection often tells lies. Do as the previous posters said and use multimc.
