The problem was solved long ago. Maybe you have some files overshadowing the ones we have provided for you. Maybe there is some other difficulty with the installation...
Romeo Papa's file did how ever also not work because;
The gametype-script he provided defines respawn to normal, which means that the deathmatch spawnpoints will be used.
vm/inf_tdm.qvm is never loaded by the game.
Even if the renamed gt_inf.vm was loaded, quess what gametype that would be??
