I have done my best to try and give you the ability to Manage Lower League teams in the USA.
The problem I came across was the American Development League, SI Have placed it in between MLS and The Second Division and you can not move it. So you can only be promoted in my Update From Third-Second and back down and so forth.
This is not my problem it is the way SI have done it, but you can still manage the following:
American Development League
National Premier Soccer League..
They are the only ones available to Add-On..
I have given it my best shot
Here is the instructions to install this database,
Click Download(Bottom) , You will get USA Lowe League.dbc
Move USA Lowe League.dbc in your Football Manager 2013 editor data folder:
Win Vista/7/8: C:\Users\\Documents\Sports Interactive\Football Manager 2013\editor data\
Win XP: C:\Documents and Settings\\My Documents\Sports Interactive\Football Manager 2013\editor data\
Mac OS X: /Users//Documents/Sports Interactive/Football Manager 2013/editor data/
Create the folder editor data if it doesn't exist.
Start your Game..
Change the Editor Data File to the USA Lowe League One, Choose USA as your Nation
Make Sure it is Default Database
Start your Database and you will have USA Lower Leagues!
Have fun guys!
Like i say there are some Promotion Errors, this will not be resolved it is SI fault the way they have done the Editor
