The Docky bar had disappeared after update

Docky version: 2.0.14~bzr1457-0ubuntu1~10.04~dockycore1
Distro: Ubuntu 10.04.2 - i386 32 bits
Gnome 2.30.2

Video Card - Nvidia GT 220 - Driver version: 270.29
X Version: 11.0 - Server vendor version: 1.7.6 (10706000)
mono-runtime - 2.4.4 ~svn151842-1ubuntu4

After I updated the dockybar, when I try to turn it on, it does not appear. When I try to turn it on through the terminal I get the following message:

homer@homer-desktop:~$ docky

And typing your command line appears:

homer@homer-desktop:~$ kill -SIGQUIT $(ps x|grep Docky.exe|grep -v grep|awk '{ print $1; }')
kill: uso: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]
