Get your taxes done using TurboTax

I've tried everything I can find but no success. I have 2 machines, one on WiFi & the other on ethernet. Same problem. I did see someone who had a problem with last year's & apparently knows a lot about programming because he found a solution in the error log & made a cmd entry to change something about the requested dns settings. I don't understand how that might relate to this year's problem, but if anyone knows & can explain it I would try.
