I have had two updates here in Austria, but previously in America I had no problem making updates. Does anyone know how I can fix this? I cannot make an overseas call from Austria, only text or email. Carol Traxler text 301 646 0721 (USA number) or caroltraxler@yahoo.com How can one "verify" a signature???

That's a bug in Microsoft Internet Information Server's FTP component. You need to install fix KB2888853 on the server. If the fix isn't applicable, use a different FTP server software (preferred, IIS is a mess), or contact Microsoft support to get a Hotfix for your OS (if still supported).
