[Q] CWM - Error 7 topic

Hey folks,
I just rooted my LG G2 International (d802) and installed cwm 6.0.4.4 touch. Now I tried to install the newest cm11 nightly, but I always get:

Status 7
Installation aborted.

I even tried editing the updater-script file, but that just gave me another error.
Any ideos how to fix this problem ?
