avast client cannot update

please Help i have avast server on win 2003 server and Xp prof + home on client PC but on client avast cannot update there is error while updating " http error …" i am wearing proxy server 192.168.?.? port 8080 how can i do for this trouble . ???

first of all write out the complete error

if it is possible to go on internet without the proxy u could try that and see if u can update without proxy, if that works then the proxy is for some reason blocking the updates…

That is kind of what I am into on my program. The license key won’t update and let me be protected. I am still looking for an answer to why they assigned it to me but won’t let it work!!
