Re: gamename already running
This is what worked for me:
1) uninstall the EA App and restart PC
2) Delete these folders (AppData is a hidden folder)
C:\Users\YOUR_USERNAME\AppData\Local\Electronic Arts
C:\Users\YOUR_USERNAME\AppData\Local\EADesktop
C:\Users\YOUR_USERNAME\AppData\Local\Origin
3) Reinstall EA app and start it; If not all of your installed games are visible then restart the client - this should populate the list.
Enjoy gaming as usual 🙂
