Problem when upgrading to pro on CentOS, how to downgrade?

[Paxa]

I'm using centos65-x86_64-20140116 from http://www.vagrantbox.es/

I installed inspeqtor run it for few days, then installed inspeqtor-pro.

When I run inspeqtorctl status - it give empty result

When try to restart service

$ initctl restart inspeqtor
initctl: Unknown job: inspeqtor

$ initctl restart inspeqtor_pro
initctl: Unknown job: inspeqtor_pro

Try list all services

$ initctl list
rc stop/waiting
tty (/dev/tty3) start/running, process 1052
tty (/dev/tty2) start/running, process 1050
tty (/dev/tty1) start/running, process 1048
tty (/dev/tty6) start/running, process 1062
tty (/dev/tty5) start/running, process 1056
tty (/dev/tty4) start/running, process 1054
plymouth-shutdown stop/waiting
control-alt-delete stop/waiting
rcS-emergency stop/waiting
kexec-disable stop/waiting
quit-plymouth stop/waiting
rcS stop/waiting
prefdm stop/waiting
init-system-dbus stop/waiting
splash-manager stop/waiting
start-ttys stop/waiting
rcS-sulogin stop/waiting
serial stop/waiting

Then I remove inspeqtor-pro and wanna inspeqtor (not pro), but it installs inspeqtor-pro

yum remove inspeqtor-pro
yum install -y inspeqtor

After I re-installed, it start working.
