Versions 2.xx are no longer supported, so either use V3B18c...18e or don't ask for the support. This topic says clearly what and how to install to get podbot menu working. If You cannot get it, I cannot repeat the same over and over again, because I would have to say this what is already written (which You cannot get). I suggest You just install
All-In-One. Then read pattiently 3 times the whole topic. The most important things are: setting up the password (to tell the server what is the password expected by podbot_mm.dll/*.so) and invoking the password (to let the server know You are the one who said the correct password) - that setinfo stuff You need to learn how it works to understand what You need to get working the main podbot menu (but also clanmod menu, amxmodmenu etc). But I'm not going to describe that again and again, because it was clearly written few times.
