Dominic,

I have RealBot (version 1.0 as well as the WIP version) running with AMX no problem. I don't know offhand what would cause the problem you're having (except for a problem with CS-Steam loading).

What I would suggest is to try to narrow down where the problem is creeping in as follows -

1 - Uninstall and Reinstall Steam
2 - Start a Counterstrike game and make sure it starts and loads a map
3 - Install MetaMod version 1.17 and then test Counterstrike again
4 - Install and configure AMX and then test Counterstrike again, also testing the AMX functions in the game
5 - DISABLE the lines in the plugins.ini file of Metamod that load the AMX DLLs
6 - Install Realbot version 1.0
7 - Configure Realbot version 1.0 to load using the old method of adding '+localinfo mm_gamedll dlls/realbot.dll' (without the quotes) to the command line for loading Counterstrike (under Launch Options for Counterstrike in Steam)
8 - Start a Counterstrike game and make sure it loads a map and that you are able to add bots
9 - Re-enable the lines in the plugins.ini file of Metamod that loads the AMX DLLs
10 - Start a Counterstrike game and test if Bots work and if AMX works as well
11 - If you have success with step 10, and you are feeling brave, then continue with step 12.
12 - Download and install the WIP version of Realbot
13 - Remove the option of '+localinfo mm_gamedll dlls/realbot.dll' from the Launch Options for Counterstrike in Steam
14 - Add the relevant line (most likely 'win32 ..\realbot\dll\realbot_mm.dll' without the quotes) to the plugins.ini file of Metamod to load Realbot with Metamod
15 - Start a Counterstrike game and see if it still works

Good luck !!
