won't add to the library

[KRIST3R]

Hey my friend. i hoped you could help me out, with why arduino doesn't wanna add the files to library. It is in dansih, but it just says that "Keypad-mester" can't be used and that it has to be ascii? even though it is. i have done it before in sketch and then "add library", but it won't with any zip file. I would really appreicate if you can help out! I have removed the second include "Keypad.h" still doesn't help ;)
