Hello and welcome to the forums. Forget qmm, use ET3.00 from Trackbase as your et installation, 2.55/2.60 http://filebase.trackbase.net/et/server/et300_README.txt The easiest way is to have a valid NQ installation first before adding this mod, we used the NQ1.2.3, (compatible with ET3.00) created that directory (which for that version is noquarter) and then remove .so or .dll and replace with the qagame.mp.i386.so for the Linux version or the qagame_mp_x86 for windows, add the .pk3 files to the noquarter directory and delete your noquater .pk3 files, start your server using the +set fs_game noquarter and exec server.cfg. Install basic et, if the servers starts then, Install ET3.00 if your server starts in ET3.00 then, Install what ever mod, if your server don't start in ET3.00 then you have not named the file correctly, If your server starts but in ETmain mode then there is an issue with your mod directory or path.
