MERGE TWO DATABASES INTO ONE MEGA DATABASE

TLDR; as the title says I'm trying to merge two databases into 1 massive database so I can start a new game. I tried merging them with the editor but I can't seem to correct the error that occurs before game setups in the main menu even though after verifying the database there was no error in the editor. 

attached below are the two files I'm trying to merge into one, and also the merged output I created if anyone could help correct this I would be eternally grateful plus anyone can use it afterwards.

If the editor data files are from the same country, you won't be able to merge them and you can only use one when starting a new career. If they aren't from the same country, there's no need to merge them and you can run them together at the same time.

I never recommend merging as I have tried many times and it always causes issues 

They aren’t from the same country (Canada-USA) but at the same time I tried running both But to no avail so I decided to merge them both since they weren’t from the same country but still no progress. The main issue is that when starting the game Both fmf files somehow interfere with each other’s league settings. Would appreciate it if you could test it. 

Yh I can see why! Did you ever find a way around any of these problems?

No it didn't work for me

Hi, so I got it all to work and if you guys are interested here is the new file. it took a little bit of time that I didn't think id put in but voila.

le piece de resistance.
