How to verify League fmf file?

Hi,

I have one file for Serbian Zone Leagues from Karna, but it's for last version of the game. The guy isn't online for like more than a month and I want to start playing now after data update but with Serbian leagues. 

I need to verify the file but I don't know how to do that. Is there anyone who can help or do that for me? I can send file in PM. 

Thanks in advance.
