Bug with publish as v8 or what?

Hello! This is my first post here, but have you already been helpfull many times.
I recently installed CS3 version and made small application to try the new version. Everything works fine in CS3, but i wanted to publish it as v8 as well, and got into the problems: all dynamic text fields are empty! I tried changing settings for the field (font rendering method) and when set to “use device fonts” i get something (but B and I formatting is lost), otherwise the content is not there.

Is this a bug, or am i doing something wrong? For now, i can’t embed any fonts when exporting to older versions?
