We have to apologize as there was a minor problem down the manufacturing chain, and the first 10,000 boxes got printed with CD key displayed in the wrong format. However - this is a minor issue, and it`s really easy to install the game.
The CD key you get with the Dawn of Fantasy DVD Box copy is in 6-5-5-5-4 format
For example: 123456-12345-12345-12345-1234
However, for the installer you need to enter your key in 5-5-5-5-5 format. Basically you are just switching - characters
We suggest writing down your key on paper in this new format to make it easier to enter. Once you are done reenter it on the installer screen
Here`s a picture:
