Huh, multiple options
[link|http://www.gaarde.org/acronyms/?lookup=H|http://www.gaarde.org/acronyms/?lookup=H] lists both expansions. And "happy to help" is definitely the way that I learned it. But from a google search, "hope this helps" is about 10x more popular than "happy to help".
Live and learn.
Cheers,
