My debugger shows:

Error #2044: SecurityErrorEvent no controlado: text=Error #2048: Violación de la       seguridad Sandbox: http://asa.com.pk/main.swf no puede cargar datos desde http://www.asa.com.pk/downloads/largeimage/mcb.gif.

Quick Google Search ended on:

Actionscript Error #2044: Unhandled SecurityErrorEvent:. text=Error #2047: Security sandbox violation: LocalConnection.send: 127.0.0.1 cannot access

I think you will get it after this, basically it's a crossdomain.xml thing.

I have tested your app, and the error it's exactly because of the flash player 10 sandbox feature, you need to use a crossdomain.xml file where you allow both domains to be cross-accessed.

Answer 2

There are a number of things you can do to fix security errors like this.

• Create a valid crossdomain.xml file under both http://domain.com & http://www.domain.com
• Set the DNS to forward http://domain.com to http://www.domain.com permanently
• In your AS code add Secuirty.allowdomain( "*" );

Hope this helps.
