My friend is having some odd problems with Forge 6.0.1.349[before it was #341] and Magic Launcher 1.0.0

Every time he tries to launch Minecraft it suddenly crashes with Forge 6.0.1.341 and now #349].

If he doesn't have any mods within the internal load out part it launches fine.

This is the error he's getting.

Missing class member: public B c, class: agl, mod: minecraftforge-universal-6.0.1.349.zip

And as far as he knows it isn't magic launcher or Minecraft itself, also he's using Java 7 which also isn't the problem.

So as far as we're concerned it has to be forge giving him some oddity problems.

 

So as it stands were at a stalemate as to how to fix the problem.

Update Forge.

We're both running the current version of forge and i can play minecraft just fine it's just

on his end the game crashes every time.

 

-=EDIT=-

Ok we both are now running 6.0.1.355

I can launch the game just fine, my friend on the other hand is still

running into problems.

He's done a fresh install of 1.4.2 and it will not launch with forge universal 6.0.1.355 as the only mod

installed.

This is the error report it gave him.

I as well am using Magic Launcher and I'm having no issues.

The only way that error happens is if he is trying to install Forge on a improper version of the Minecraft jar.

So, he need to cleanup and make sure he has the 1.4.2 jar.

The oddity is that he does have 1.4.2 minecraft.jar file.

He deleted the .minecraft folder and ran the default launcher to get it again.

But he still has that issue.

What I'm thinking is that it's Java 7, but that's just me.

Java 7 has nothing to do with this, its a screwed up install.

 

Try again without magiclauncher. I personally use [lmgtfy]MultiMC[/lmgtfy].
