HELP! Technic Launcher problem!

[Fatalops]

So whenever I try to launch a modpack on the technic launcher it goes back to the technic launcher modpack screen. So i cant really open any modpacks or play them too because of this problem. I also set my launcher's ram to 4gbs out of the 8 i have. Please please help me, thank you!

Please provide more information than "its broke".  What mod packs, got any logs that you've posted on pastebin? A bit more details on the error.

That's not to mention that you need logs, and you need to put this in the Tracker rather than on the forums.
