When you try to sync your Zune, a problem may occur where you get the following error:

Can’t use your Zune Pass with this Zune because you have three other Zune devices already using it. To update the devices for this account, click your Zune tag and select Computers and devices.

You can only sync with a total of 3 devices. One of the devices must be removed. To do so, try the following steps:

1. In the Zune software, Click Sign In, and then enter your credentials.

2. Click Settings > Computers and Devices.

3. Click Remove for the device you want to remove. Click OK when you’re done.

You should now be able to associate a new device with your Zune Pass as well as sync it.
