Firstly, ensure that the top of the file has the same basic structure as shown in the screenshot below. Small variations may exist between versions.

Bear in mind that the spaces in front of the factions are attributed to the tab key. This is to the left of the Q key on the keyboard. If no spaces exist, or they were created using the space bar, delete the existing spaces before the faction's name and press the tab key to insert the correct type of spacing.






If that doesn't work, as Sheildmaiden has said, it would be useful to know what the version of your game is.

To check this, go to the "Options" menu on the start of the game. In the top left hand corner, there should be a number. This number is the version of the game.

Once you've retrieved the version post it in this thread for us to look at.

Good luck
