"Confirm Payment" DOES NOT WORK!

I am trying to file my return after using your fing product, and at the final step, after putting in my CC information it hangs on a grayed out screen, as if there is an error.   All fields are filled in.  There is no error presented.    I have entered this information 8 or 9 times now.   I have used two different browsers, each with "incognito" windows so there are no cache or cookie memories.

 

This is pathetic.
