Minecraft forge 1.6.4 won't run
Hi guys can you please help me with this issue ;
So, I downloaded mc forge for 1.6.4 (auto installer- recommended) and it says minecraft forge installed successfully' then I go to latest launcher> select profile> forge 1.6.4 ( it says something like 'ready to play forge 1.6.4 something something something) and then I press play and THE LAUNCHER CLOSES WITHOUT STARTING THE GAME!! So frustrating. No error log. No game.
Info
I use the new launcher
Use recommended forge installer 1.6.4
Use latest java

Java 8 doesn't agree with the Forge apparently so use Java 7, it seems to work for me

Ok thanks
At the Forge profile on the launcher select so the launcher doesnt close when the game starts that way you can get the error log, then post it here
I tried this because I am having the same problem (in 1.7.2) however the launcher does nothing. It does not give me an error report or anything.
