I have a small SWF hosted on GameFS that contains an advertisement, and I load in that small swf in my game (so I can change the ads after the game is released). When I'm testing the game locally using FlashDevelop the small swf loads fine. When I put the game swf on my server and access the game from there it is unable to load the small swf. In FireFox it says "read cdn.playerio.com" for a long time, and then that goes away and nothing has been loaded. The swf that's being loaded is only 1.5kb, it should load nearly instantly (and does when testing locally). I tried putting Security.allowDomain("*") and Security.allowInsecureDomain("*"), but that didn't help.
I'm ready to show this game to a client as soon as the advertisement swf can successfully load, so all help is appreciated.
