I've purchased, installed and activated PhpEd Professional Advantage 5.5 on Windows XP. Help>About says "5.5 build 5524" and Help>"Registration information" confirms "All features are now enabled".

However, in the section "Opening files, projects and workspaces" in the "Nusphere PhpEd Manual" in the help tab, links such as "SFTP" and "WebDAV" are grayed out and say "Not available - This feature is available in Professional version only".

When I browse through the documentation in the help tab, I see documentation that appears to be of an older version. For example, the section "Dynamic layout change in PhpED" says "NuSphere PhpED 5.0 features new improved workspace layout", and indeed some of the text and screenshot appear to be outdated.

What do I need to do to get the actual 5.5 Professional documentation?
