Nope i installed EUI in the DLC folder like the guide said and everything in the Mods folder
That's really strange - never seen such bug report in this thread before. Can you post a screenshot of your whole screen? Does the interface look the same as in the play-through video you referred to? Are the city banners the only quirks? How about the tech tree? Is it (a little bit) different from the vanilla one?
Also don't you have the regular (non-CBP) EUI installed as well? If yes, they might conflict.
And what do you mean by that you could not install CBP with the auto-installer? Any errors during the setup or the game does not start with it? This should be the easiest way, especially if your Civ5 and Steam are all in the standard folders.
