I am trying to play a station (http://kpcclive1.publicradio.org:80/) on a button click. This works when I execute directly from the flash tool using Ctrl+ENTER option. This also works when I run the corresponding .swf file in browser plugin. However it is not working after building .air file (air 2) and install it. Does this has anything to do with digital signing of .air file? Or do I missing anything? Please help. This is just a proof of concept attempt.
