Thanks for the replies.

I already have 'realbot max 11' in my bot.cfg file, and it was all working fine before. However, for some reason, it seems that the bot.cfg file is not being read when the server starts up (normally, there would be Realbot specific stuff in the server console as the server started up, as quoted in my previous post, but now there is not).

The server worked fine before, but (I think) since the last Steam update it don't work.

I even installed CS-1.5 and tried RB WIP#6 on it and it works fine. Seems the problem is only with CS 1.6 HLDS
