In the "Connect to" window type your user name and password (you have got in your registration e-mail). If you want your computer automatically save your login information for next session, set the "Save password" item.
Leave the "Domain" empty, and then click "Ok".

If you get the following message, you will have to reinstall Service Pack 6a and reboot the system.

Notice1: To provide high-level 128-bit data encrypting we recommend you to download and install the High Encryption version for Service Pack 6a.
Before you try to obtain or install High Encryption version, verify which platform your computer based on:
Intel (x86) Dec Alpha

Notice2: 128-bit encryption is included in the latest versions of the Internet Explorer browser (5.5 and later). If you are running an earlier version of Internet Explorer without 128-bit encryption, you can download the latest version of Internet Explorer from the Internet Explorer Downloads page or upgrade your present browser with the Internet Explorer High Encryption Pack. It will allow to avoid any conflicts of enciphering modes of Internet Explorer and Windows.
