Keyboard doesn't work with tehnic launcher

[camj]

When i use any modpack (or even vanilla) through the launcher as soon is a create a world my keyboard doesn't work at all. All i can do is look around and break/place blocks (the mouse works). Does anyone have any idea how I can resolve this issue?

LWJGL may be corrupted, go to the .technic folder, and delete the cache folder presented there. it should redownload the necessary library files.
