Oh man, how stupid I am 
Off course, now I understood, I changed the name of the class CameraRig.uc to killCam.uc
I did not know that you can have a custom class as a variable type in Unreal Script.
I was reading on udn about variable types (UDK | UnrealScriptVariables), so I thought that the variable types were just like these:
byte
int
bool
float
string
constant
But now I understood better.
Thanks man, trully thanks, I will fix this now.
Cheers
