So I completely cleaned out my minecraft folder. Then i reinstalled it and downloaded forge 1.6.4 and did the usual procedure. I launched minecraft and it was good. Everything was fine till i went to launch forge. I clicked play and i saw the bar loading. Then the screen disappeared, as expected. But then the Mojang screen didnt show. And the Minecraft title screen didnt show. I waited but the screen never popped up. I've reinstalled everything several times but nothing haappened. I need help! The only reason i still love minecraft is because of mods!! Help please!!

Any help on the proper way to update it?

And i also tried it out on other forge installs. 1.7.10 actually works, but 1.7.2 doesn't. Will that solve this problem as well? I'm not sure how to get them to work properly like before. Most of my mods are 1.7.2 and below anyway so i really appreciate the help.

*waves magic wand*

Everything 'works' now.

That is all we can do unless you provide us with the logs like we ask -.-

That's just it. No error logs pop up. Just emptiness. I cleaned minecraft and reinstalled, downloaded forge 1.6.4 client, and tried to play it. I don't know what to give you guys cause i dont see anything to give.

1) We dont support 1.6.4 -.-

2) THere is ALWAYS a log of some kind, there are these awesome things on your launcher called tabs. One of them being 'Developer Logs' you know cuz its kinda freakin important.

I finallly found out what was frickin wrong!!!!!! I was using the wrong version of 1.6.4. I was trying to use 1.6.4 forge 9.11.1.965. But there was another version,forge 9.11.0.833, so I tried it and the angels started to sing! Thanks guys for the help!
