Writing files in air for android

Question

I'm trying to create a user license agreement that will show the first time a player opens my game. I'm using a FileStream with a complete event and an IOEvent. The IOEvent is triggered the first time because the file I'm looking for doesn't exist. I then show the user agreement and write the file to the application storage directory. If I then close the game and open it a second time I expect the Complete event to fire since the file now exists but instead the IOEvent is firing again. Why isn't it finding the file and triggering the complete event? I can read the file after I create it so I know it exists at that point.
import flash.filesystem.File;
import flash.filesystem.FileStream;
import flash.filesystem.FileMode;
import flash.events.Event;
import flash.events.IOErrorEvent;
import flash.utils.ByteArray;
//load ula file
var file:File = File.applicationStorageDirectory;
file.resolvePath("version.txt");
var version:String = "1.0";
var stream:FileStream = new FileStream();
stream.addEventListener(Event.COMPLETE, checkVersion);
stream.addEventListener(IOErrorEvent.IO_ERROR, noVersion);
stream.openAsync(file,FileMode.UPDATE);
function checkVersion(e:Event):void{
        testText.text += "found file";
        stream.removeEventListener(Event.COMPLETE, checkVersion);
        stream.removeEventListener(IOErrorEvent.IO_ERROR, noVersion);
        var ver:String = e.target.readUTFBytes(e.target.bytesAvailable);
        if(ver == version.toString()){
                stream.close();
                file = null;
                stream = null;
                testText.text += "goto splash screen";
                //gotoAndStop("SplashScreen");
        else{
                stream.writeUTFBytes(String(version));
                stream.close();
                file = null;
                stream = null;
                testText.text += "wrong version number";
                //ula.testText.text = "writing file version = "+version;
                //ula.visible = true;
function noVersion(e:IOErrorEvent):void{
        stream.removeEventListener(Event.COMPLETE, checkVersion);
        stream.removeEventListener(IOErrorEvent.IO_ERROR, noVersion);
        testText.text += "file doesn't exist error = "+e.text;
        stream.close();
        file = null;
        stream = null;
        var file2:File = File.applicationStorageDirectory.resolvePath("version.txt");
        var stream2:FileStream = new FileStream();
        stream2.open(file2, FileMode.WRITE);
        stream2.writeUTFBytes(version);
        stream2.close();
        file2 = null;
        stream2 = null;
        testText.text += "   created file";
 }

I use this
var f:File= new File(File.documentsDirectory.resolvePath("RunBit.csv").url);
    if (!f.exists) {
        //Create file
CHECK THE PERMISSIONS
