Im very sad, my NIS2009 live update cannot complete

Hello guys, I hope you can help me. I installed NIS2009 as an upgrade of my NIS2008. The transition is smooth. The problem is my pulse update  is not working. Everytime i press the "Run Live Update" botton, a norton live update window appears and within a few seconds it says "Unable to connect to Norton Live update Server. Please check your internet connection." The "Check for updates" item is marked "X" and the status says "Failed to complete". I dont have this problem with my NIS2008. I tried uninstalling and re-installing. Still no joy. Please show me how to solve this problem. Our NIS2009 in the office works flawlessly. Im using a HP laptop with 4Gb of memory running on Windows Vista Hope Premium. Im connecto to the internet via  3G wireless modem.

 

Thank you
