Can you Fix it?, this error[@cheeseh] Options

[Price]

Hey cheeseh, first i want to thank you for the great bot, but now its not working anymore.
The Team fortress 2 bot isnt working, if i use this one
http://code.google.com/p/rcbot2/downloads/list
it loads, but after typing "rcbot addbot" into the console.
The game crashs, except if you type "rcbot_stop 1" before you addbot then you can add a bot but the bots do nothing because the stop command.
I wanna tell you the error, it says
HandleCommand_JoinClass( undefined ) - invalid class name.
*
You get this error nonstop if you add a bot and if you don't type "rcbot_stop 1", then this* message and -> crash)
Please fix it, that would be great.
Good luck and greetings
