Hardcore Mode Error

Hello again,

i wanted to add the hardcore mode system, which was released [Only registered and activated users can see links. Click Here To Register...].
I think i copy and pasted everything, but for some reason something is missing, i checked it even twice.

Code:

c:\flyff\Source\Program\Neuz\DPLoginClient.cpp(188): error C2065: 'nMode' : undeclared identifier

c:\flyff\Source\Program\Neuz\DPLoginClient.cpp(188): error C2593: 'operator <<' is ambiguous

        while trying to match the argument list '(CAr, 'unknown-type')'

Where do i have to add the 'nMode' ?
And what is the second error?

Line of both errors:

Code:

#ifdef __HARDCORE_MODE
	ar << nMode;
#endif
