So this edit will eliminate these 2 problems guys, and just to let you know I haven’t edited anything else apart from this issue. I edited this with Football manager 2014 Editor from Steam so it's guaranteed will never ever give error or problems.
To use Edit Data’s you always need to start new games otherwise new game unfortunately, because when you start the game the edit is added on to the game, that creates a games for you, it’s like a data that’s started and half way complete you can’t add an extra part as this would Corrupt complete game, give it errors, making it unplayable.
Step 1Downloaded "79_nations_in_eu_fm14_56890.dbc" and move it in your Football Manager 2014 editor data folder:
Win Vista/7: C:\Users\<username>\Documents\Sports Interactive\Football Manager 2014\editor data\
Win XP: C:\Documents and Settings\<username>\My Documents\Sports Interactive\Football Manager 2014\editor data\
Mac OS X: /Users/<username>/Documents/Sports Interactive/Football Manager 2014/editor data/
Create the folder "editor data" if it doesn't exist.
Step 2Start a new career game (won't work with classic mode).
A little pop-up window will come up that says there is 1 enabled editor file. Click OK.
