BleepingComputer.com: Kaspersky get Strucked when run Update

I have a Cyber Cafe, I've purchased a Licensed version of Kaspersky 6. for Workstations and used for about two years. I have license until 22 April 2009.

One of the new computers I got with Win XP SP3 and I've installed the Kaspersky 6 in there, during installation I'm used to update the kaspersky with a downloaded Cumul, Weekly & Daily updates giving the path to the Flash Drive. (Which I'm Sure Virus Free, as I have Kaspersky updated versions in every computer)

after the installations are done and the computer is restarted (required by the installation) I normally run the update thru internet, and that time it failed.

I can successfully load and scan the System and other drives with kaspersky with existing definitions. but could not update by any means (manual, Automatically, or Downloaded files)

Hope that somebody could help me to solve the problem.

Other computers in my network with win XP SP2 and kaspersky 6 workstation could run update without any problem. (for cyber cafe users convenience I've remove the installation of proactive defense while installing in all computers.)


Thanks
