For exporting the" click here to activate" button wont work, its the button that allows you to upload more then 30 second videos
That's odd, it should normally show the activation helper - a separate application window.
If you go to Options/Preferences > Activation tab > Activate, does that do anything?
How about when you initially open Express, does the activation window show then?
(If you'll excuse the edit, I've added to your thread title a bit, to make it clearer for other users)
