[F]Steam conectivity problems

I have my account tied to my steam account, but when i try to connect afther todays patch the client gives me a “bad client version” error. So i am supposed to download the newest version, but im not sure how can manualy do that on steam. Am i missing something?

go to the game website with the site button on the login screen.  I’m having to do that right now since they apparently did not include an auto patcher program for some really odd reason.
