Did you mean UN able to download zAlternator?
Yes. There it is VERY easy to move all your music from WMP to zune. All you have to do is...
1.) Find out where your music is stored on the computer.
2.) Then Open up zune software and click settings.
3.) Under the music catagory select Add Folder then navigate to the folder where you music is and select it.
4.) Click OK and then your music will begin to import.
Hope this helped.
