yup. It opens zune and plays it, but there's still nothng in my collection.
You've probably already tried this, but here's some instructions I found on Yahoo Answers (source link at the bottom) to import music from the iTunes Library. It involves selecting some Advanced Settings, so I hope this helps!
If your iTunes library does not automatically migrate to your Zune library, you must manually add your iTunes folder to the list of monitored folders.
To add a folder to the Zune library, follow these steps:
1. Open the Zune software.
2. On the Options menu, click Add Folder to Library.
3. Zune shows a list of the folders that it currently checks for new media files. To add a folder to the list, click Add Folder, select the folder that you want to add, and then click OK.
4. Click Advanced Options.
5. Make sure that the Add files, playlists, and ratings from another media player to library check box is selected.
6. Click OK.
