Need help with embedded fonts

This is the example straight out of the Adobe livedocs. All I’ve done is change the font to be embedded. It works with Times New Roman, but not Helvetica or several other fonts. I haven’t found an explanation yet as to …

  1. why I can’t embed a font like TrajanPro-Bold.otf with this code in Flex Builder 2 but
  2. I was able to embed it when using FB3 beta and
  3. why specifying other fonts, Helvetica included, leads to a “… possibly undefined property fadein …” error in FB2 but Times New Roman works just fine.

Thanks in advance for any help.
