KANZENFUUTEN

So i tried using my email instead of my username and it seems to be logging on now, i feel stupid but it may be working now

So, my situation is, the first time i tried hexxit, it allowed me to play offline, now it won't log me in because it can't connect to minecraft.net. I am using the same username and password as my mojang account. it has been at the launching screen for 30 min thus far and says launching but is failing to do so. Please help.
