Sorry for bringing this topic up again, but I am having the same issues.

Here's everything I did in order:

1. I downloaded and installed MetaMod 1.17 in directory C:\Program Files\Steam\SteamApps\<my e-mail address>\counter-strike\cstrike\addons\metamod\dlls\metamod.dll

2. Downloaded and installed AI 1.0 in directory C:\Program Files\Steam\SteamApps\<my e-mail address>\counter-strike

3. Edited the liblist.gam file in directory C:\Program Files\Steam\SteamApps\<my e-mail address>\counter-strike\cstrike, changing:
gamedll "dlls/mp.dll" gamedll_linux "dlls/cs_i386.so"
to
gamedll "addons/metamod/dlls/metamod.dll" gamedll_linux "addons/metamod/dlls/metamod_i386.so"and made the file read-only.

4. I activated the ACTIVATECS16.BAT file.

5. I start-up Counter-Strike from the "Games" menu from Steam, start a new game, press H and no menu or anything comes up.
