ZPatchBuilder failed + cannot find patch info + md5 system.mrs wrong

[iSh0otZz]

Hello,
i use nationalgunz server files and client
i configured everything up, i had some complications but im thought it with gunz.exe
with "anti-hack system.mrs md5 is wrong!" i just downloaded a gunz.exe from the forum for direct runnable
but i would like to force players to start with gunzlauncher so if someone have solution for "anti-hack system.mrs md5 is wrong!" will be awesome and i'll be thankful
now for the other problem im facing after getting other gunz.exe (runnable)
i configured gunzlauncher.exe
when i launch it, it waits a bit: analyzing patch info
then cannot find patch info :
