Avast 6 Not Updating

[technoankur]

Hi Guys !I'm using Avast Internet Security 6 from last 4 months !! Yesterday i formatted my laptop and installed it but i found that its not updating automatically !
then i tried updating it manually but that din't worked !
I checked the firewall settings and found everything correct !! I unistalled the Avast and cleaned up the registry and then installed it but again its not working !!
When i'm connected to internet for the whole day it does not update but as soon i'm disconnected the error box pops out and says 'the last update was unsuccessful and...................."

Tell me what to do guys !! :'(
