Can't start a game

[htc]

I had a issue with a texturepack but I solved it already, downloaded a modded pack of Pure BD Craft and it does load perfectly, I also decided to delete everything and starting again with the Technic launcher.

Game loads fine, changed the texture pack with no problem whatsover.

When I try to start a new game it freezes on the building terrain. I don't know what to do to solve it.

Forgot to add it doesn't show "Not answering" on the Tekkit Lite program, I had it trying to create a new world for over half an hour without an error message or not answering but it didn't really load anything.
