State tax filing

This fix is for a state that has been downloaded but won't install.  My situation (and, I believe) that of the original poster) is that I can't purchase the state return I need.  In my case, I try to "Start" my state return, the "State Purchase" window opens.  I select the state I want, click "Continue" (twice) and get "...select Continue and we'll get your billing and payment info..."  When I click continue, assuming I'm about to pay for the state return, all I get is "Hmm... it looks like we've hit a slight snag.  Please try again or check back in a bit."  The system won't let me purchase my state return.
