Mac Hexxit problem

[DeathJR]

So i downloaded a launcher for mac and it worked fine last night (the night i downloaded it) but today it suddenly decided to act up. At first it kept crashing so i updated my java thinking it would help, but now it wont even load it just shows me a black screen and wont progress any further. Any ideas?
