Hi, I had the same problem and found this workaround (thanks to emregan’s hint “it seems the plugin got deactivated”):
first remove the wpcf7_add_shortcode function from functions.php, upgrade contact form 7 and reactivate. Then you can put back the function and the shortcode works. (i’m on wordpress 4.0 and contact form 3.9.3

I’m having the same problem, updated to 3.5.3. Suggested solution didn’t work for me.
