kicks me out

I am playing a game with my girlfriend and we were playing without any trouble, from one moment to another, the server started to kick me out everytime the day finished (this started happening after the day 25 of winter first year, the gift day). From now on, everytime the day finished, it kicks...

i can go about the town and walk around the house but as soon as i get near the barn area, the game freezes then exits out the game. I didnt do anything different besides update the game through steam ???
