Sometimes this error can be caused by software on your computer that slows down the network connection. This error can also appear if you are downloading multiple items. I'd like to provide some steps that should help you successfully download your purchases.

It often helps to pause the download and then download items one at a time. These steps will walk you through doing this:

1) Open iTunes.

2) From the Store menu at the top, choose Check for Available Downloads. If you're unable to upgrade and are using iTunes 7, the option will say Check for Purchases.

3) Enter your account name and password, then click Check. Your purchases should begin downloading.

4) Under the STORE section on the left, click Downloads.

5) Click the Pause All button in the lower-right corner. This will temporarily pause all of your downloads.

6) To resume only one of the downloads, click the refresh button that appears to the right of one of the paused downloads.

Certain types of software can affect the way a computer sends and receives information from the Internet. Here are a few examples of these types of software:

• Firewalls
• Web accelerators
• Ad filters
• Virus protection software

If you have any of this kind of software installed on your computer, you will need to configure each of the applications to allow your internet connection to access iTunes freely. For instructions, please refer to the documentation that came with that software, or contact the software's manufacturer. You'll need to configure the software to allow these domains to send and receive data from the Internet freely:

itunes.apple.com
ax.itunes.apple.com

For assistance in configuring your firewall or accelerator software, you may need to contact the manufacturer or your Internet service provider (ISP). When contacting their support representatives, it may be useful to have the following information:

Once you have managed to allow access to iTunes through other software, please follow these instructions:

1) Sign out of the iTunes Store.

2) Quit the iTunes application.

3) Restart your computer.

4) Open iTunes.

5) Select Check for Available Downloads from the Store menu at the top of iTunes, (if you're unable to upgrade and are using iTunes 7, you'll choose Check for Purchases).

If you can't find this option, you can also click this link to do the same thing:

6) Enter your account name and password, then click Check. The missing item should begin downloading and appear in your Purchased playlist.

Please note that the iTunes Store cannot investigate every user's connection issue. Apple Discussions are another source of information about iTunes, where everyone from new users to professionals can interact and share their knowledge and experiences. You may find another user with the same operating system or ISP that may be able to help resolve this issue. You can find the iTunes discussions group at:

If you are using a dial-up connection, you might consider downloading your purchases over a broadband connection, if you have access to one.

The 306 error is most commonly related to an Internet Connection problem. Make sure that iTunes is not being blocked by any sort of firewall or antivirus software that you have.
