Spore Galactic Adventures does not work with EA App

@JulenArtano THIS! Thank you, this is the only solution that worked for me.

Uninstalling EA optional, you only need to close it from taskbar.

I've been also struggling with locale. But you can change it in the old Origin app!
My Game Library -> Right click on Galactic Adventures -> Properties -> in Advanced Launch Options, enter "-L -en-us"
