Edited rules not allowing tech tree

[Mementh]

HI i am new to civ 3 and i am just learning... i want to edit the maps i make and make the other civilizaitions less agressive... thats all right now....

but if i just make it use its own rules and not the default rules then it makes the tech tree look very odd and you can't click on anything...

HELP
