Problem creating new leagues on MM

I have created new leagues on MM. When I star a career mode the game turns off. I give them new IDs (not replaced) and I have ensured to get all right.

 

I do not understand this program very well, but maybe Robson Mambrini can help you.

 

First what is MM ?
second do you have lua files for the teams created ?

 

I wanted to say MW. And i have lua files

 

Create with creation master and be sure all files are edited even team formation
