My Minecraft Launcher isn't working? - 1

I'm using the launcher given on minecraft.net to play, but it won't work. I tried to install a few mods like smart moving and mo creatures along with the morphing mod, and i noticed that it doesn't reach the title screen. I thought that it was just crashing, but no, its not even crashing, I've had a crash screen before. Anyways, the launcher just acts normal as if it would play, but then it just closes and re-opens. (Note: i had mods before this happened and it worked just fine.) I tried to remove the mods i tried to install leaving the mods i already had, but it still wouldnt work. I tried a few suggestions, ( like logging out and logging back in) but that didn't work. I Updated Java like 10 mminutes ago, which i tried after doing, that didn't work. I just wanted to know if there was a way to fix it.
