Yep
From what I could gather (if you're still having the issue, that is), is that this error message is caused by either file corruption or antivirus interference (mainly downloaded ones like Norton, Avast, etc.)
Could you please check for me that the folder the game is located on is listed as "trusted" in whatever antivirus software you use? Try redownloading the game to a trusted folder if the previous tip did not work.
