I have tried using this CSDM beta on latest CS:CZ on Steam with latest AMXMODX.
I use it and its okay, gameplay is good, but there is a bug - I cannot access CSDM settings. The console keeps saying "Server tried to send invalid command:"csdm_sett_menu" when I type in console csdm_menu and press 2.
I noticed this problem too. I cannot configure the plugin via menu.
