Flash AS3 Getting Security sandbox violation when trying fetch an external swf

Hii, I'm tring to load swf file to my flash application from a different server. When i try to load it on flash IDE (crl+enter) everything is working fine, but when i run the swf as an independent swf file or by debugging it, i'm getting this error:

SecurityError: Error #2121: Security sandbox violation: LoaderInfo.content: file:///C|/Users/something/Desktop/blablabla/myplayer.swf cannot access http://www.somedomain.com/blablabla/lalalala/abc.swf. This may be worked around by calling Security.allowDomain.
at flash.display::LoaderInfo/get content()
at wallplayer_fla::MainTimeline/swfLoaded()[wallplayer_fla.MainTimeline::frame1:216]
Cannot display source code at this location.

I have the crossdomain.xml file in the root of my server:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
    <allow-access-from domain="*" />
</cross-domain-policy>

In "myplayer.swf" I have:

Security.allowDomain("*");
Security.allowInsecureDomain("*");
...
...
var loaderContext:LoaderContext = new LoaderContext();
loaderContext.checkPolicyFile = true;
loaderContext.allowCodeImport = true;

ldr = new Loader();
ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, swfLoaded);
ldr.load(new URLRequest(graySwfFilename), loaderContext);
...
...
var mcExt;
var ldr:Loader;
function swfLoaded(e:Event):void {
    mcExt = MovieClip(ldr.contentLoaderInfo.content);
    ldr.contentLoaderInfo.removeEventListener(Event.COMPLETE, swfLoaded);
    mcExt.x = 0;
    mcExt.y = 0;
    addChild(mcExt);
}

I don't really know what to do... Please HELP?

Your error is from the external location not having a cross domain file, not you. Check out this tutorial on using a bridge file to communicate with an external api. I used as3 and php in this example. The trick is to maintain control of the cross domain file on your domain.Then let your server communicate with the api.

Solution: for Flex 4.x (Currently 4.6) and AS3 in Flash Builder:

    import flash.system.SecurityDomain;
    import flash.system.ApplicationDomain;
    import flash.system.LoaderContext;
    var loaderContext:LoaderContext = new LoaderContext();
    loaderContext.applicationDomain = ApplicationDomain.currentDomain;
    loaderContext.securityDomain = SecurityDomain.currentDomain; // Sets the security

context to resolve Error # 2121

... now load your SWF with 

loader.load(new URLRequest(webServerWebURL),loaderContext);

Add your working folder in the Global Security Settings panel. This allows you to load external files from a single SWF in your file system. Its the same if you want a.swf to load b.swf even if they is located in the same folder.

This will allow your SWF to read external files.

This should not be a problem if you upload you SWF to a server though.
