Your Movie information is out of date.
I was checking on Argo the movie today Nov. 1st and the showtimes said the the movie will be out as of the 2nd. This movie has been out for several weeks. I cross checked it with Fandango and that is correct.
Could you let us know where is your location and which theatres are you usually go to so that we can try to troubleshoot this issue?
