You need to setup an rcon password on your server first.
Check it by joining your server and typing
[code:56f08]rcon xx status[/code:56f08]
where xx is your password
If you receive a list of clients and their info then your rcon password is working
Just add your rcon password ( just the password ) to the field in the autokick program
If you need more info on rcon check out my guide over at MOHadmin.com
