Can anyone help me please? I have set up a network on my Windows XP computer to my wife's Vista Premium laptop.

The connectivity is great and she has no trouble searching the Net on it. Unfortuantely, since I set it up she can no longer recieve emails from Incredimail and her virus checker refuses to update. Although she can run a scan, she can't even get into the online help which refuses to connect. I have tried to reinstall Incredimail and have even put her a new virus checker on, but the story is excatly the same.

She was on AVG for free and I have now installed The Sheild Deluxe. Any suggestions would be gratefully received.
