Fail2ban will not start

Following some thread on the 'net, I found that my fail2ban was installed or updated by some other repo, so I uninstalled it.. Removed the /etc/fail2ban directory that was left over, removed it from Plesk's installation utility and re-installed it using the same utility.

However, I noticed it was not running.. So I did a "service fail2ban start", and it gets stuck.. I waited for 5 minutes..

[root@pluto ~]# service fail2ban start
Starting fail2ban:
(stuck here)

Here is how it looks:
# ps...
