a problem with dumprom and HTC (Windows Mobile 6 Extract)

[accepted]

HI

i downloaded WM6CB and extract it now i have 2 nbf file

nk.nbf 64MB Size
ms.nbf 10MB Size (Empty_Extended_rom)

i want to extract these

I tested dumprom.exe and HTC64 Extended ROM Tool.exe but i can't extract these

if i use dumprom then i can't extract it when i use HTC64 and i use dumprom with nk.fat file argument then i can extract some files and get this error

i used this arguments

For NBF File
dumprom nk.nbf -d mydirectory\
dumprom -5 nk.nbf -d mydirectory\

For FAT File
dumprom -5 nk.fat -d mydirectory\
dumprom nk.fat -d mydirectory\

And I can't Extract Empty Rom with this way
