Unhappy [Q] CWM Error Status code 7

Hi, I want to flash on my p990 KitKat ROM (ParanoidROM) and when i try to install zip from my sd card it says set_metadata_recursive: some changes failed (Status 7). I've searched that error and I found that it occures when flashing any KitKat ROM, can someone help, how to fix that? SlimKat ROM flashes without problem...
