SWF movie not loading properly.

Question

I decided to use a loader method for a flash project. When I load swf files from a folder on my computer into my main movie, it loads just fine. However, when I try to load the same exact swf files from a remote server, the script fails on me giving me an error like this:
TypeError: Error #1034: Type Coercion failed: cannot convert Com@2f949bc9 to Com.
. I had imagined that this was due to security domains, so I had tried something like this:
ldd = new Loader();
             var ret:URLRequest = new URLRequest(""path"Object.swf");   
             var lddContent:LoaderContext = new LoaderContext();
             lddContent.securityDomain = SecurityDomain.currentDomain;
             lddContent.applicationDomain = ApplicationDomain.currentDomain;
             ldd.contentLoaderInfo.addEventListener(Event.COMPLETE, completeHandling);
             ldd.load(ret, lddContent);
             Object.addChild(ldd);
All this does is give me this:
SecurityError: Error #2142: Security sandbox violation: local SWF files cannot use the LoaderContext.securityDomain property. file:
-although everywhere states it should work.
I even have makeshift class files for those SWF's on the server with   Security.allowDomain(["*"]);
in their constructors, and still nothing.
What in the world am I missing?

Answer 1

I'm gonna spell this out sweet and golden, because with painstaking effort, I solved this problem.
1. When importing swf's that you've made from a remote site, and those SWF classes use custom classes, specific calls do not work:
For example:
var = classname(event.target(whatever you load)) // a cast like this won't work
method(var:className) nor will this work....
Instead:
Simply use: var = (event.target etc);
and
method(var:Object)
2. Furthermore, if you're testing files on a remote website in your flash API on your computer, please keep in mind that even if you update, change, or delete files on the remote server, flash has a recent history record or those files, much like a browser. Flash will not realize that you've changed those files until you've closed it down and opened it again.
3. Using remote files in the flash API, SecurityDomains etc are unnecessary. But when using flash player, you must use one of the several methods for Security Sandboxes.
I used:
Security.allowDomain(["*"]);
Thanks to everybody who attempted to help, and I hope this helps others as well.
and with that....I'm onto my next project.
See you guys in a couple of weeks!
