The problem is the "podbot_mm.dll" is running well but u cant add any bot!!!
Method1:Get the correct botweapon.cfg from someone who can run his pod correctly.Then overwrite yours with it.
If this doesn't work, u can try method2:Get every *.cfg file in your cs dic (from a friend who can run pod correctly) and overwrite...
Although it seems dull, u may solve the problem.
