No specific info about version 2.1. Please visit the main page of PES 2013 Editor on Software Informer.
I used to be able to change team names in PES 2013 using PES 2013 editor 2.0
But then I had some bugs and had to install a new version of the game and now I can't change the team names.
In the program it's changed but no change in the game takes place when I open it. Any help? I use PES Edit 6.0 patch.
