System font changes to web font in responsive project when published? Any way to change this? (Mac)

Hi!

Im relatively new to using Adobe Captivate, recently purchased Adobe captivate 9 and I am having some issues.

I am creating a e learning project for my University and theres a certain font I have selected (Helvetica Neue) for the title page.

When I actually preview the project, its automatically changed back to Web font Helvetica

Is there a way to use system font throughout the project without it changing when it is actually published?

Thank You!
