ok, you go to

and download the latest bot + client. They are in the announcements on the left hand side of the page. Put the client in your silkroad folder, and install the bot to where ever u want.
now, download and watch this video about setting up a bot account. U can get here by opening the thing called 'charge' from wherever u installed the bot.
now once u have done that double click on the white finger. Wait a few secs and check ur system tray. Thats at the bottom of ur screen on the right, those little icons next to the clock. Look for the white finger and right click it. Select start game.
Login and everything like usual. When u get ingame press the 'home' key on your keyboard. In the general tab (it should be the default one of startup anyway) enter the username and pw of the bot account that you just created. tick the box that says 'connect to backup server' then click login. The auto training button will become clickable and now u can bot ^_^ enjoy
