These are the messages from FZ that may give a clue to what is wrong:
Response: 150 Opening ASCII mode data connection.
Response: 550 The supplied message is incomplete. The signature was not verified.
Error: File transfer failed

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 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).

FTP connection problems? Do yourself a favor and read Network Configuration.
