Hello, Im following your guide since I have a smiliar problem with EA App I guess, Im interested in another game (NFS Payback bought from Steam) but Im still following your suggestions as I cant really launch the game. I already purchased NFS Heat before February, but no problems there, played it fully.
After connecting Steam to EA App, I click on "Play" after few seconds a messagge appears "Preparing game" then nothing happens, no error. Just briefly EA tells me that some functions have been disabled since I launch the game from another platform (same happens if I launch from EA App).
While looking at Task Manager, for few seconds NFS process appears and disappears right after.
I tried all basic solutions (uninstall/reinstall game and EA App, tried clear cache, App repair, Updating and all your suggestions since now, but Ill try once again to be sure).
I thank you for trying to help, If there's something more I can try please let me know.
