Make sure you are using the correct recovery for your device.
To flash KitKat Roms you need at least CWM 22.214.171.124 or newer, same for CWM based recoverys.
Latest PhilZ Touch will work too to flash KitKat too.
Else try TWRP 126.96.36.199.
Some recoverys in my thread, link in my signature.
CWM Swipe will get an update later or tomorrow to 188.8.131.52 Swipe
