1. You've probably added a minister/leader/techteam/anyother thing using the ID number = 19800 .
But this ID is already used for the same kind of thing (or minister/or leader/or techteam... etc, whatewer you have added), so you have a duplicate input. You need to change the ID number of the last 19800 you added in.
Also, beware with the range of avaliable ID's in DH. They're defined by nation. Make sure you're adding an ID that fits for the nation! Check the modding documentation to get sure about it.
2. It seems that you've added a techteam to the game. Maybe you've not put the correct numbers of ";" after the last technology component of your new tech team. This may cause that the game is reading the "x" (that closes the line) as a tech component. Check it out.
If you added some new technologies, then the problem can also be there, istead of in the tech teams file.
3. You can use a Reichkom. as base for a new nation. But in this case you'll need to edit the files that control the realesing stuff, like revolt.txt and others to make sure that other countries but Germany will release that country.
Maybe the best way to follow is add a new country in an unused slot, like U00.
Of course you'll have to edit revolt.txt and other files too (like mobilization ones), but it's a new nation after all...
Hope it helps.
