I cant put music in my zen mp3

What do you mean that it is not there?
Do you mean the autoplay screen thing that pops up when putting in a mp3?
If it doesnt pop up then click on the start button and then go to computer and look for a zen usb name

you probably need the disk it came with and if you cant find it look for it on the internet and you might wanna try a program called WINAMP to transfer music to your ipod

You should put in the istallation cd before hooking it up. Then afterwards, it will ask you how you want to put music on your Zen when you hook it up.

Hope this helps.

I think I found my answer. With my player connected I went to Control Panel- System- Hardware- Device Manager and under Portable Devices removed my Zen Player. I then went back to Control Panel- Add Hardware- and let the Add Hardware Wizard add my player back.
My Zen Micro Photo now connects to computer and I can charge the battery with no problem.

Before coneccting player to the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard. It worked for mine ! GOOD LUCK

why dont you reformat the player?or reset it..some player have a reset..

down load the new red button firmware from the creative site and load it onto the player, this should format the whole thing, you will lose your music though

replace usb cable that comes with it with new one.or check connector of your mp3

Hmmm when you plug it in to put music on it do you use the sync manager thing? thats what i use and sometimes it says theres no player connected even though there is, so i just keep plugging and unplugging until it works.. but then if that doesnt work i just go to  "Zen v series media explorer" it like lets you upload music there too.. hope you find something that works! 

First thing you wanna do is to try another set of headphones. If it still sounds muffled then theres a fault in the audio output section and these things are non user serviceable. Your gonna need to send back to the manufacturer. Good Luck
