If you have a firewall installed on your computer or network, then it is possible that iTunes displays "Error -3259" and won't download the lessons.

This error is not caused by the PrepCast™ security - it is caused by firewalls on your computer or network. Here is what you can do:

• Are you trying to download the PrepCast™ on your office computer? Your company probably has a firewall in place that prohibits the download of podcast video files. You can speak to your network administrator and ask for an exception or you can download the PrepCast™ from another computer that does not have a firewall installed. For instance at home or on a friend's computer.

• Are you trying to download the PrepCast™ on your home computer? Open your firewall and change the settings to allow all traffic from http://www.prepcastfiles.info. If you don't know how to do that, you can also turn your firewall off for a few minutes, download all PrepCast™ episodes and then restart the firewall. But be careful! If you turn the firewall off, then your computer is unprotected. Changing the settings to allow traffic is always the better solution. (Note: some anti-virus software packages also have built-in firewall features that you may have to turn off temporarily.)

We are sorry that we cannot help you fix this error. It is caused by the security settings on your computer which we cannot access and change for you.
