Question using fonts and FMX 2004

I wanted to make sure I had all the fonts I needed so I opened up the Photoshop CS file provided to me by the client. This file has all the fonts in them. I do have all the fonts I need installed on my system. However when I try to use the font in Flash I can not find the font in the drop down menu in Flash. I suppose Flash does not support this font. If I can not find/select the font in the drop down menu does that mean that Flash does not support the font and I can’t use that font in Flash? Also, is there any other way to embed and use that font in a flash movie?
