Game won't load! Help?

What you were expecting to happen, and what actually happened?
I click on the icon to open my game, it starts to open then appears to crash and go off the screen… this has been this way for the past few days. I didn’t make any changes so I don’t know what to think.
What are the steps to make it happen again? I restarted my computer, I checked to see if Steam was logged in, and it still just crashes and won’t fully open. I just see the start screen and boom it goes off!

Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
