1 .download the metamod dll from
www.metamod.org and put in the directory "cstrike\addons\metamod\dlls" then open your liblist.gam file in notepad and change the line "gamedll" to read "addons\metamod\dlls\metamod.dll" instead of "dlls\mp.dll"
that was the metamod installation procedure now lets move on the podbot mm installation.
2 . download PMB's fixed podbot and unzip the archive to your "cstrike\addons" directory.
Then go to your "cstrike\addons\metamod" directory and create a new textdocument and type in the line:
"win32 addons\podbot\podbot_mm.dll" without the quotes and save it.
then rename the file to "plugins.ini" without the quotes and make sure that you are not hiding file extensions on all of your other files because if you are your file would really be called plugins.ini.txt which would not work.
3. start up CS and frag some bots
