Is Technic broken?

[AlctenZeta]

I wanted to play Hexxit, but it said I had to update it. I tried to update, but it came up with an error. This also happened with Attack of the B-Team. I went on Hexxit without updating, but when I want on to a world, it said all the Natura mods were missing. I still got on to a world, but all of the dirt and grass that normally spawned in was gone, thus corrupting my entire world. I then uninstalled Hexxit, to see if that would work, only to realize that the Discover module was missing. This means that I am missing Hexxit and have no way to get it back. For attack of the B-Team, this happened: http://gyazo.com/d8687257f6d988320cefb1777f7ecfa3      I was not even able to log on. I do, in fact, have it installed. It would be very helpful if you could fix these issues. Thank you.
