You should not permit ftp access to the root (or any login users) account. You should instead install sshd, ssh to your machine as a normal user, then use the su command to obtain super user privs. I don't know what "FTP Pro" is and you did not say what distro your server or client are using so I can't provide explicit instructions on how to install ssh.
However as an example, if your server is Debian based:
Code:
apt-get install openssh-server
And if your client is Debian based:
Code:
apt-get install openssh-client
