now it worked !! Thank you very very much for the quick help!
I still have one question though. the zombie plague mod consists of an .amxx file that is active from 7 p.m. to 6 a.m.
but if I want to install a deatchmatch mod now, for example
a deathmatch server has several .amxx files:
csdm_equip.amxx
csdm_main.amxx
and so forth...
how can I solve that?
would be very grateful if you could help me again!
