Title Screen/Main Menu not loading on start up?

[AshCraft1337]

When I launch Tekkit Legends, it doesn't respond. Afterwards, i'm greeted with a black screen (which is supposed to be the MOJANG screen)

Afterwards, it shows a white screen with a small part of the title screen on the bottom left.

The buttons work, but they are not visible, and when you click them, they make the clicking sound, but since the whole screen is white you cant see anything.

 

Please help.

I've added an attachment for you guys to see what i mean.
