The AVA.exe you've downloaded is outdated that's why this error is shown.
To prevent this problem from happening in the future; you need to disable Firewall & Anti-virus before starting AVA and its highly recommended to change your anti-virus if you use AVG because this issue is mostly caused by AVG.
Link for an updated AVA.exe : http://the-lounge.netii.net/AVA.rar
I'm completely responsible for this link, its on my FTP.
Hope that helped, Please inform me back if the problem hasn't been fixed.
