CAL can not reboot

Hello,
i have installed the Comodo Antivirus for linux. V1.1 268025.1
I meet two problems:
1. COMODO Application Agent is not running!
2.Filesystem filter driver is not loaded
All problems are fixed after i installed the kernel-devel and gcc packages and then the program is OK.
But after i reboot my computer, I meet these two problems again, after i run the /opt/COMODO/post_setup.sh,
the program is OK.
This is a strange problem,How to solve it?
Thanks!

     by the way, I use opensuse 12.2

Permissions on a file .sh what?
