Game won't launch after hours of play

[Lizsieuk]

I don't know what to do or where I post this.

I have unistalled the game and reinstalled it about 4 times now, I have validated my game, I have uninstalled steam and reinstalled steam, I've gone on public test and gone off it. Grounded starts like it's launching and then I'm back to steam page. I'm so stuck I've been playing since August and never had a problem until now. Can anyone help me please.
