I followed the instructions in the link and LiveUpdate seems to be working again. When I run [Download LiveUpdate Content - Download], I get the results below.
LiveUpdate succeeded. [Site: My Site]
LUALL.EXE finished running. [Site: My Site]
There were no new content updates. Return code = 1. [Site: My Site]
LUALL.EXE has been launched. [Site: My Site]
Download started. [Site: My Site]
However, when go to [Show LiveUpdate Downloads], it still shows old virus and spyware definition dates. I think I'm really close to getting it work as it should but I still need your help guys. Thanks.
