Sorry if I'm starting to annoy you, but I just got into this stuff and I really don't know all the files and stuff. Could you explain to me step by step what I need to do?
About what you should do: set up first German East Africa. About the instructions please refer to the web site linked and the code quoted in this thread. About the provinces IDs please see my post above.
Last, if for any difficulty you may have instead of trying to understand the problem you keep asking, as this is not a chat, you waste your time and the time of others.
