Hi, I have a problem with Forge. I install it, all good, but when I start Minecraft with the profile of Forge, it load, but Minecraft don't start. I see the fml-client-latest and:

What I can do?

 

Seriously. 3 posts down: http://www.minecraftforge.net/forum/index.php/topic,22757.msg115269.html#msg115269

 

I'm using Java 7 -- Update 61, and I don't see the solution in the EAQ, sorry.

 

And I don't have any mod, only Forge.

I have verified in java.com...

Version 7, Update 67

 

But ok, I will uninstall Java and install a previous version...

Then make sure you ONLY have Java 7 update 67 installed. And nothing more.
