help! can not update database

??? Please help somebody.

I just bought avast and installed it to my laptop. When i want to update virus database, it comes the message with:

Cannot connect to download696.avast.com (174.133.38.42:80).

What should i do?

Thanks.

Did you add the registry key?
Which is your firewall?

what do you mean by registry key? is it same as license key? if license key. Yes i did put successfully.

the firewall is from windows. And i turned it off while i tried to update database. but still not success.

apparently, i just manually enter this link from mozilla : http://www.avast.com/eng/updates.html and now trying to download the virus database manually. hoping this will be success.

my question is: why when i try to update virus database from avast program directly, it failed?

really appreciate for all the replies.
