Upgrade from CS4 to CS5: Dynamically created text isn´t shown anymore.

Question

Hello,
since I have updated my Flash CS4 to CS5, textfields that have been dynamically created inside external classes aren´t filled with text anymore. At least they exist; the cursor appears, when I roll over the place, where it has been placed.
This is how I place it:
1. The font is embeded as Font-Symbol inside the library. Name: "BertholdWalbaumBook", Linkage: "BertholdWalbaumBook";
2. Code:
          moreInfoButtonText = new TextField();
          moreInfoButtonText.text = "More Info";
               //TEXTFORMAT
            var pre_Disco_RecordStandard_TextFormat:TextFormat = new TextFormat();
            pre_Disco_RecordStandard_TextFormat.align = TextFormatAlign.LEFT;
            pre_Disco_RecordStandard_TextFormat.color = "FFFFFF";
            pre_Disco_RecordStandard_TextFormat.font = "BertholdWalbaumBook";
            pre_Disco_RecordStandard_TextFormat.leading = 3;
            pre_Disco_RecordStandard_TextFormat.size = 14.62;
            pre_Disco_RecordStandard_TextFormat.letterSpacing = 0;
            //COORDINATES
            moreInfoButtonText.x = moreInfoButtonBG.x+5;
            moreInfoButtonText.y = moreInfoButtonBG.y-30;
          //TEXTFIELD
            moreInfoButtonText.embedFonts = true;
            moreInfoButtonText.setTextFormat(pre_Disco_RecordStandard_TextFormat);
            moreInfoButtonText.antiAliasType = AntiAliasType.ADVANCED;
            moreInfoButtonText.sharpness = -400;
            moreInfoButtonText.thickness = -200;
            moreInfoButtonText.autoSize = TextFieldAutoSize.RIGHT;
            moreInfoButtonText.wordWrap = true;
            moreInfoButtonText.multiline = false;
          //ADD CHILD
            addChild(moreInfoButtonText);
When I set       moreInfoButtonText.embedFonts = false;    the text is shown with system font, so the problem must cohere with embedding.
