Get your taxes done using TurboTax

Sometimes it sends me back to the login screen, which leads to the splash screen "Welcome back to turbo tax for another year!", but in some attempts it has just taken me directly to the splash screen.  In either case the splash screen only lasts a few seconds, followed by the attached.  I can find no way to proceed forward that doesn't end up in exactly the same death spiral.  I have tried clearing all cookies, with no noticeable impact.
