look man :
You are on locked bootloader . also when you flash this Rom you format your System through CWM . so your CWM gone .
Solution . if you don't want to Flash it every time you flash a new Rom Unlock your bootloader and install a custom Kerne like LuPuS or Kappa or any Kernel in Development section
if you will still locked . flash it every time you flash a new Rom
Hope this helped
