You are trying to startup a dedicated server or listenserver (You will play on this PC or it will be the server only)? You should get back to work Your AMX MOD X 1.60, then read
this topic how to install metamod (there is also info how to install manually podbot). That line
win32 addons/podbot/podbot_mm.dll
should be in the file
addons\
metamod\plugin
s.ini
(not in the addons folder and not plugin.ini).
Also the line in liblist.gam should call Your metamod this way:
gamedll "addons\metamod\dlls\metamod.dll"
Make sure You didn't add any "gamedll" option to Your CS1.6 shortcut properites of command line.
