Finally the v1.0.4! After some nightly builds (that didn't work for me) a new version of MTA. I preferred the chatbox of the other version even if you can change it in the other one .
You have to put it in:
C:\Program Files\MTA San Andreas\server\mods\deathmatch\resources\ (this is the default directory)
Then start the server (C:\Program Files\MTA San Andreas\server\) and write "start gatemarker" (without quotes).
