Ok, you have Commercial 6.31.4 and your WED version is 6.269.
That makes more sense.

We have a rash of warez users that come to these boards with all manner of crazy "warezed" versions and when you post "Commercial 6.269", well, red flags come up.
No, you have the latest update, but it sounds like your computer is missing a file. Try reinstalling 3DGS completely and see if that solves it. If not, the problem is with your OS instalation.
