When I am in the game and click on the tech tree, it takes about a minute to load and some of the techs say "Missing Info" instead of the name of the tech.  I selected verify integrity of game files and it replied that 3 files failed to validate and will be reacquired.  Run verify a second time and all is well, the files are fixed.  Turn the game on and have the same problem.  Turn it off and verify integrity and 3 files need fixing again.  I turned off Steam Cloud synchronization, deleted the directory for the game from My Games, uninstalled the game, and reinstalled it.  The problem remains the same.  I have not even had the game very long, but it was working yesterday.  When I play a previously saved game it works fine, but I can't start a new game because the tech tree is always broken.  How do I fix this?
