What's wrong with my minecraft? - 2

So, the other day my servers stopped connecting or working, so i deleted my.minecraft file and delted minecraft, then i reinstalled it, after i did the minecraft won't load, the blue downloading bar comes up to install the files, but then the blue bar vanishes and nothing happening, i press play again then it does the same thing, it just says its installing files and then vanishes. I have played minecraft for months and its been fine, what is happening, how do i fix this? I have updated my Java and done everything with that? I'm running windows 7

You could try using the technic launcher. Just look up technic packs or something. There are many mod packs they have, also. Just check it out, it should work. I think it actually uses a different location than.minecaft, too.
