I can try to help you if you give me a detailed description of what you did, but the first thing you should do is to undo everything and apply the changes one at a time. This will most likely deliver you with the solution.
By no means did I expect you to fix it for me, I just thought it would be easier and quicker if I showed you what I had done rather than explaining it. Sorry if I gave the wrong impression

Basically I've added most of the North American continent, the terrain map comes to 1001x851. I'm positive all the other map sizes are correct.

Firstly I was getting a CTD once the loading bar had gone all the way across, and I pinned this down to there being one giant province. Once I removed a lot of the terrain (leaving Central America) it loaded fine. So I added 19 more random provinces named one, two, three etc. I've added these to descr_sound_music_types, descr_regions, imperial_campaign_regions_and_settlement_names, descr_regions_and_settlement_name_lookup and descr strat. With this last one I just copy and pasted all the stuff from your City, like buildings and stuff, to the new provinces.
