Te, How did you get the beta-test version of conquest anyway? I though Firaxis will take those away.
Anyway, the only way I see is to try to convert the game to conquest 1.15b(the latest version?) and see if the same problems persist. Maybe you should try the unpacth verssion of conquest too, because it will be the closest thing to the beta-test version. Finally I think you should tell one of the mayor problems you have in different forums, see if anyone can help you figure them out.
The only thing left I have to say is don't give up, we are here for you.
