Sorry if you're already aware of this but I just wanted to let you know if not. I just renewed a license for ESS on Vista. When transferring the new password into the appropriate box, no apparent change occurred. However, virus signature definitions update occurred successfully, even though the expiry date shown was 'invalid' and the taskbar icon red. The resolution of this was to copy and paste the username (even though it was the same), as well as the password into the renewal box and all turned a pleasant green. Thanks, Michael.
