Tekkit won't load for mac

[TheOnlyLobo]

I downloaded tekkit launcher and it brought me up to the login screen just fine. But when I put in my username and password, the screen just goes away. I tried looking around to see if I can get this problem fixed but I couldn't find anything. Can anyone help me figure this out?

You are supposed to post problems on one of the BUG boards. I think that you are having a launcher issue, but I am not really sure.

If you saw the Mojang screen then the launcher worked and the error is with one of the modpacks.
