I created a new database and added new league but everytime I want to start a new game this shows up and I can't pick the league.
Can anyone help me?
Looks like you've got an editor file loaded because of the yellow triangle, that could be causing it. Try changing what editor files your using as you create the new game, set it so no custom databases are selected to see if its that whats causing it. If that doesn't fix I'd recommend reinstalling FM.
