Had a look at the site, couldn't really tell from the contact page what could be causing the issue(s). It could just be that my system has the font in question already installed. However, I looked at the fla as well and the text fields in the contact form need to have the fonts embedded. Really quite simple to do. Just select one of the text fields and then have a look at the "Properties" panel, if it's not already open in a side menu, try pressing "Control + F3" on Windows (probably "Command F3" on the Mac, but don't hold me to it). Once the Properties panel is visible, look for the heading "CHARACTER", should be in bold letters. Within that area, there should be an "EMBED..." button, hit it and a new dialog box should appear. Look under "CHARACTER RANGES" and select from the list the different glyphs that should be embedded into the text field. Usually, "Uppercase", "Lowercase", "Numerals" and "Punctuation" are the only ones I ever select. Repeat for all dynamic or input text fields.

HTH.
