Software hangs when I try to pay for state e-file with credit card

Software hangs when I try to pay for state e-file with credit card.  Was able to file US taxes electronically by themselves.  Went back to try state alone and same problem.  I get a pop-up window in the TurboTax app that says it will take me to the online store.  My system switches to an open browser but nothing opens.  The TT pop-up is frozen.  Close pop-up and try again, same deal.  Tried clearing cookies and cache, restarting app, rebooting.  Got tech support who advised changing screen resolution and there may be something to that.  It may just not be displaying properly, making it look like it is frozen but I tried many different resolutions and could never get it to work.  I'm putting a lot of my effort into trying to give Intuit my $25.  You think they would make THAT part easy.
