SteamWorld Build Mechanized DLC

I purchased the game on the 4th. Same day it came out and i played until yesterday.When I started yesterday it booted out to the title screen and i can't play anymore it just keeps booting me out i played the game approximately 40 hrs. I could start a new game but if it does it again after playing a while than i'm back to square one got any ideas for me cause the game is "great" i love it, If that didn't happen i would give it 5 stars.I'm disappointed cause i really want to play this game so help me out OK. Thanks

Base game is fire. Why do gamers hate new things😢😢😢
