Technic Launcher Will Not Load (Mac)

[1beastdestroyer]

So, heres the problem. I love playing on the Technic Launcher, but recently it has stopped working. When I double-click the jar icon, it does the enlarging then disappearing thing, but no application starts up. The "Start" icon does not appear in my toolbar, and I've tried everything to fix it. I tried updating my java, but nothing works. Please help.
