Courier-Imap on Apache CentOS VPS with Kloxo is not working

I am having a problem with my email service... the courier-imap seems to be not working. Whenever i enable it via Kloxo panel .. It seems to stop itself. I tried to restart via SSH but no luck...

It outputs the following code..

[root@server1 ~]# service courier-imap restart
Stopping Courier-Imap:

/etc/init.d/courier-imap: line 45: cd: /var/qmail/supervise/imap4-ssl/: No such file or directory
chmod: cannot access `run': No such file or directory

Any solutions for this problem...
