Its attempting to do some downloads, sample files. These all live in a manifest which list 13 different files to download. These all get downloaded one at a time, like this:

	Server.cleanFinishedDownloads();
	writeLog("----Server online status:" + Server.isOnline());
	writeLog("--------Server pending downloads:" + trace(Server.getPendingDownloads()));
	writeLog("--------Server pending calls:" + trace(Server.getPendingCalls()));
	writeLog("Downloading " + (targetStep+1) + " of " +  setupManifest.setupSteps.length + " Files");	
	// ok so here is where we will do the actual download...
	// 
	theDownloadedFile = USERDOWNLOAD_FOLDER_OBJ.getChildFile(setupManifest.setupSteps[targetStep].downloadFileDestination);
	writeLog("Downloading " + setupManifest.setupSteps[targetStep].downloadFileDestination + "...");
			
	theDownload = Server.downloadFile(setupManifest.setupSteps[targetStep].downloadFileName,{},theDownloadedFile,function()
	{
		writeLog("in the download process..... " + theDownloadedFile + "...");
              // a bunch of other stuff here.....
       };

As you can see its writing a log file, when I look at the users log file, I get this:

----Server online status:1
--------Server pending downloads:[]
--------Server pending calls:[]
Downloading 1 of 13 Files
Downloading HorizenDataT01.sfc...

So the server is online, and the first file to download is discovered, but its just not entering the download function, but for me its saying:

----Server online status:1
--------Server pending downloads:[]
--------Server pending calls:[]
Downloading 1 of 13 Files
Downloading HorizenDataT01.sfc...
in the download process..... Object 0xb4322628...
Downloaded Object 0xb4322628
Downloading 2 of 13 Files
Downloading HorizenDataT02.sfc...
in the download process..... Object 0xb43189c8...
Downloaded Object 0xb43189c8
Downloading 3 of 13 Files
Downloading HorizenDataT03.sfc...
in the download process..... Object 0xb4316fb8...
Downloaded Object 0xb4316fb8
Downloading 4 of 13 Files
Downloading HorizenDataT04.sfc...
in the download process..... Object 0xb431d7f8...
Downloaded Object 0xb431d7f8
Downloading 5 of 13 Files
Downloading HorizenDataT05.sfc...
in the download process..... Object 0xb4320c18...
etc...etc..

So for me it IS entering the download function and executing correctly. The user says there's no calls being recorded in his firewall... has anyone got ANY ideas?
