ActionScript 3.0 :: Error #2112: Provided Parameter LoaderContext.ApplicationDomain Is From A Disallowed Domain

So with the help of others, I figured out the runtime font loading issue, and all was working great.Until we moved to the live environment, where apparently Flash is freaking out if I load my swfs from [URL]..

Can anyone tell me what I need to do to fix this? Here's the error:

Code:SecurityError: Error #2112: Provided parameter LoaderContext.ApplicationDomain is from a disallowed domain. In short, here's the structure. A Wrapper swf is embedded on a page.The Wrapper loads a child Player swf into a separate Application Domain, and then calls a public init() function in the Player to get things rolling, passing into the Player swf a reference to that newly-created ApplicationDomain the player was loaded into.At some point the Player decides whether or not it needs to load an external font Library swf for embedding subtitle fonts. It loads the font(s) as needed into the same ApplicationDomain that was passed into it (should be the same one it was loaded in itself, no?).

Once again, I've tried all sorts of combinations of code changes, but nothing seems to be fixing it. It all comes down to whether or not the original Wrapper swf is embedded via "www.domain.com" or "domain.com".

FYI, I have a crossdomain.xml file set up allowing both combinations of the domain name, and in each loaded swf (the Player and the font Libraries) I have a Security.allowDomain(); set with both combinations of the domain name as well. I resolved a similar security error similarly (a different externally-loaded swf), but that doesn't seem to be working for this.
