You are having a problem with the Software Activation process for a Mediafour software product.
There are four likely causes:
1) You aren’t connected to the Internet while activating, or
2) You are connected to the Internet through a proxy, which is common on business networks, or
3) You have already installed the software on the allowed number of computers (typically just one), or
4) You have replaced enough hardware in your computer that it appears to the activation system that you are now installing the software on a second computer, even though you are not.
1) Confirm that you have an active Internet connection before attempting to activate the software.
2) Confirm that the activation wizard knows your Internet proxy information, which you can likely get from your system administrator if you are on a business network.
3) If you are using MacDrive 7.2.5 (or newer, including MacDrive 8 and 9) or XPlay 3.1.4 (or newer), and activated through the Internet, uninstalling will also allow you to deactivate automatically if your computer is still connected to the Internet. Please click here for more information.
4) If you are using MacDrive 8.0.6 (or newer, including MacDrive 9), you may deactivate without uninstalling by going to Start > All Programs > MacDrive 8 > Deactivate MacDrive.
5) Purchase additional software for the other computers from shop.mediafour.com.
6) Contact Mediafour Support, explain what has changed in your computer, and provide your product serial number. A Mediafour Support Professional will work with you to get the software activated.
