HELP! Uploading AS3 Game to server, no sound and Spacebar doesn´t work HELP!

Question

Hello, relatively new to AS3 and flash, this is the first time i am publishing anything. We are trying to upload our simple flashgame to our webserver, the game works perfectly fine locally save for one thing. We get an error regarding TLF which says it wont stream or something. So when it gets online, no sounds play and spacebar doesn't work, left and right arrow does work. We have three TLF text fields that are used to update score, lives and show you final score. If i turn these into classical text they stop working.
Things we have tried: Changing default linkage from RLS to Merged into code, changing the text boxes to classical text(they then stop working), made sure the paths are correct(all files are in the same directory including the .swz file)
This is the code from the soundclass:
package 
    import flash.net.URLRequest;
    import flash.media.Sound;
    import flash.media.SoundChannel;
    import flash.events.*;
    public class MySound
        private var bgSound:Sound;
        private var fireSound:Sound;
        private var waterSound:Sound;
        private var earthSound:Sound;
        private var lightSound:Sound;
        private var soundChannel:SoundChannel;
        public function MySound()
            soundChannel = new SoundChannel();
            bgSound = new Sound();
            var req:URLRequest = new URLRequest("BackgroundSound.mp3");
            bgSound.load(req);
            //fire
            fireSound = new Sound();
            var req2:URLRequest = new URLRequest("soundFire.mp3");
            fireSound.load(req2);
            // water
            waterSound = new Sound();
            var req3:URLRequest = new URLRequest("soundWater.mp3");
            waterSound.load(req3);
            // earth
            earthSound = new Sound();
            var req4:URLRequest = new URLRequest("soundEarth.mp3");
            earthSound.load(req4);
            // light
            lightSound = new Sound();
            var req5:URLRequest = new URLRequest("soundLight.mp3");
            lightSound.load(req5);
        public function playBgSound()
            soundChannel = bgSound.play(0, 999999);
        public function stopBgSound()
            soundChannel.stop();
        public function playFireSound()
            fireSound.play();
        public function playWaterSound()
            waterSound.play();
        public function playEarthSound()
            earthSound.play();
        public function playLightSound()
            lightSound.play();
I can somewhat get that sound can bugg out, but why does spacebar stop functioning? ANy help is greatly appreciated as this has to be delivered in twelve hours(published online) for a school assignment.

Also might add publishing it locally in my own browser everything works, as does ofcourse playing it in flash itself. Changing from RLS to merged into code stops the error from coming, but doesn´t fix the problem on the server.
Code from main class related to sound and spacebar:
import flash.display.*;
    import flash.events.*;
    import flash.ui.Keyboard;
    import flash.text.TextField;
    import flash.media.Sound;
    import flash.net.URLRequest;
    import flash.events.MouseEvent;
    import flash.utils.Timer;
    import flash.events.TimerEvent;
    public class main extends MovieClip
        private var fireTimer:Timer; //delay between shots
        private var canFire:Boolean = true;
        private var mySound:MySound;
        private var bulletSpeed:Number = -450;
          public function main()
            //load sounds
            mySound = new MySound();
        private function playGame(event:MouseEvent)
            gotoAndStop(2);
            // initialize
            myLives = 5;
            myHitsNo = 0;
            weaponType = 1;
            mybullets = new Array();
            enemys = new Array();       
            myScoreTxt.text = "Score: " + myHitsNo;
            myLivesTxt.text = "Lives: " + myLives;   
            fireTimer = new Timer(400, 1);
            fireTimer.addEventListener(TimerEvent.TIMER, shootTimerHandler, false, 0, true);
            stage.addEventListener(KeyboardEvent.KEY_DOWN, listenKeyDown);
            stage.addEventListener(Event.ENTER_FRAME, addEnemy);
            stage.addEventListener(Event.ENTER_FRAME, checkCollision);   
            player = new thePlayer(stage.stageWidth-40, spawnPoint2);// stage.stageHeight/2);
            stage.focus = player;
            addChild(player);
            mySound.playBgSound();
public function listenKeyDown(event:KeyboardEvent)  // Controls and weapontype selector
            if (event.keyCode == 37) //left
                player.movethePlayerDown();
            if (event.keyCode == 39) //right
                player.movethePlayerUp();
if (event.keyCode == Keyboard.SPACE) //space
                shootBullet();
                //soundFX.attachSound("Pistol Fire.wav");
                //soundFX.start();
