It seem that the update is wrong, you can try the following.
1 - uninstall the game and install it again to the original version. (Do not update it)
2 - download and update with this patch

that patch should update the original install version to the latest patch.
Note: I'm unsure if it will work for you but you can try it. if it doesn't work you should do what Gypsy39 said.
