Hello Christine,

in order to download the latest version of the software you need to attach your WebsiteX5 licence to your answers profile. Probably you used a different email address for registering the software and for registering on answers.

You can try to log in in answers with the email you used for registering WebsiteX5 and you should be able to download the latest version of the software form the download section of your profile.

In any case (assuming you have the evo version) you can download the upgrade  from here:http://www.websitex5.com/download/v9/wsx5_ev.exe

Hope this helps
