That is not what they said. They said they would provide a patch that would work with the steam version. I believe you still have to download and install it manually.
So what you're saying is they aren't distributing this patch to people who purchased this game through Steam using the Steam update system? Even though he said in his post that they were? I bought the game through Steam with the expectation that when a patch is released, it will be provided through the Steam update service. That's what it's for. And yes, the .exe of the Steam version is 1.4.9.70.
