Web page content is not displayed

[apinae]

I'm a newbie in Flash technology.
When running my first Flex project in FB4, the Main page is displayed empty, with no content, I put on it. I followed an example directly     
May it be caused by trial version of FB? Or something else...?

If you can provide bit more information about how you're trying to run your app, I may be able to help.

Are you running the app from the "run" button? Is it launching a browser window or the standalone Flash Player? Is the SWF and a corresponding HTML file in your bin-debug folder? Can you post the code for your Application MXML document?
