NIS 2011 Crashed...!

Hi all,

 

I have using NIS 2011 in a couples month. The issue happened when i tried to turn off the smart firewall, it had a big chance about 40% to crash with a report "symantec framework stop working..." . It's often happens after i update the new version of NIS 18.5.0.125, and i usually need to turn off smart firewall.

 

What's wrong ? How can i fix it?

 

My OS is windows 7 ultimate x32 (sp1 RTM) with all updates.
