1. Download
All-In-One (it comes with metamod, podbot m and AMX X).
2. Stop the CS on Your server
3. Unzip all the crap from All-In-One zip into the main "cstrike" or "czero" folder (depanding of the mod You are playing). Let overwrite all files.
4. Start the CS on Your server and type ones more:
meta list
If that doesn't help, more than likely You are installing everything in the wrong folder.
NOTE:
All-In-One needs to be installed in the main "cstrike" or "czero" folder. The
fullpack (if You have metamod already installed) needs to be installed in the ...\cstrike\addons (or ...\czero\addons) folder. That's the main difference. No confusion.
