1) Do not put space in your folder names ; the game may not work well with them
2) You just use the new way to position lines.
But if you use the old way, IIRC, the camera parameters are saved in your Tennis.ini and you have to copy them to your Stadium.ini .
I couldn't understand the new way, then for it I cameback to the old way, but I don't found information in Tennis.ini, because according to what I checked, enabling DevMode in the "XKT" profile is possible adjust lines in the game, If I try to make the same in the "Tennis.ini" this doesn't enable the shortcuts, the shortcuts are enabled with XKT profile for me.
My problem is that doesn't save changes of modification of camera.
