Savfl definitions update problem

Hello,

I run savfl 1.0.13 and when i try to run:
/opt/Symantec/symantec_antivirus/sav liveupdate -u
Than i get the following error:
"Command failed: problem with LiveUpdate
Check that java directory is in path
Unable to perform update"

I googled this error and found that i need to run:
/opt/Symantec/symantec_antivirus/update_java_home.sh
After I run it the file /etc/liveupdate.conf was restored to default that the file is empty.
Now I'm stuck.

Any help will be greatful.
