What can I do when I get the message "Bitte wählen..."

Hello

I have an Android 2.3.5 device with Flash Player 11.1.111.10 in German. Since a few weeks I got the message "Bitte wählen..." when Iwant to start to view a TV in the App Teleboy TV and I cannot continue to view anything. The people from Teleboy TV told me that this is a problem of the Flash Player. But what can I do to overcome this problem? What do I have to choose, where from and also how? I tried to change the Flash Player settings (local storage and peer-assisted-networking) but none has really helped.

Any hint is welcome.

Thanks, Sax-OMan
