Hello John,

Do you get this message in the Preview?

If yes then try to install the Flash Player Plugin in the Preview Browser by opening it and then visiting the following page:

http://get2.adobe.com/flashplayer/

Also if the message says that there's a plugin installed proceed to install this one.

Please keep me updated.

Yes, I do get this message in the preview. Now do you think this problem may be solve after is publish? I am running Flash 11 (reinstalled, reboot, same problem). Your video tutorial is very handy, what are the chances to have more of them in the future? ¡Gracias Claudio!

I forgot to mention the script message: Couldn't Load Plug-in.

WEbsitex5 v10 macht die Vorschau mit Chromium (Ursprungsbrowser für Google Chrom). Um zu Testen ob das plugin im Chrom fehlt, können Sie den Link aus der Vorschau kopieren und im einem andern Browser öffnen (Vorschau offenlassen). Ich vermute, dass in Chromium das Plugin fehlt. dies kann durch Installation von Google Chrom und darin Aktivierung des Plugin  behoben werden.

Beispiel einer Kopie Link aus Vorschau:

http://127.0.0.1:8080/index.html

Ich kopiere oft den Link um diverse Browser vor dem Veröffentlichen zu testen.

Gruss JJ
