How should I develop my units to defeat a Knight?

To be honest, I tried making maps, but I can't figure out the settings... I think I've set everything up correctly on the map, but it doesn't appear in the game. What could be the problem? There are also some difficult words in English (I do know it, though)... If needed, I can help in any way I can (we need to get people to submit maps, but will version 3.0 somehow affect things if others are using 3.1)? I'll be available this evening around 9 PM Moscow time... I can turn on Hamachi if needed.
