Programa Para Cortar Audios

I have played Sims 4 offline, without internet for a long while. It is only recently, in the past month or so, that I have not being able to play offline no matter what I do. I do not have internet at home, so anytime I need to update or want to purchase new content, I have to travel to a place that has free wi-fi. So this new bug is really frustrating. I thought my game needed updates or clearing. I have the most updated version and everything works FINE once I have internet connection. Are there steps I can take to fix this?
