Thank you for the future reference.
However, I have entered steam and chosen the "Verify integrity of game files" and this error screen still appears. I noticed all of the comments on this fix have game CACHE, not files. Is this something? I am still confused.
I will try uninstalling the game and reinstalling it.
My problem is like many others in this area, but Rage Hook Plugin is telling me my game version is 0. I have the Steam version, and I KNOW it is v1032, which this Rage Hook Plugin is supporting. What is going on here?
