Can you tell us why it not work?

If you have access to your game server's console, type the following in the server console:

1. version
2. meta list
3. meta version
4. amxx list
5. amxx version

1. Paste here the entire result from the *version, *cvarlist, *meta list, *meta game,
   *meta version, *amxx list, *amxx cvars, *amxx modules and *amxx version commands.
   
   

If you don't have access the your game's server's console, join your server and type the
following in your game console:

• rcon_password "your_rcon_password"
• rcon version
• rcon meta list
• rcon meta version
• rcon amxx list
• rcon amxx version
