Did You try to remove at all podbot folder and install it from scratch? I mean - delete whole podbot folder, then download fullpack R2B46d and uznip it to addons directory (the zip file contains podbot folder and all necessary sub-folders/files).
Hint - if You are creating a dedicated server, You need to have everything for metamod installed in:
...\SteamApps\your@email\dedicated server\cstrike\addons\
but when You try to create a listenserver, You need to have everything for metamod installed in:
...\SteamApps\your@email\counter-strike\cstrike\addons\

Can You make some screenshots from Your folders: addons, metamod, podbot (but as jpg files) to show me the structure and contents of them?

[EDIT]
Are You absolutely sure You are using legall Steam CS1.6? If it's CS1.6 Non-Steam - we will not able to help you. This forum doesn't support Non-Steam CS1.6.
