Did you activate TurboTax before you checked for updates?
Does your computer meet all of the Minimum System Requirements?
Are you using Windows in S mode? You cannot run TurboTax in S mode.
What kind of internet connection do you have? Is it broadband (fiber or cable)?
If none of this helps, please call TurboTax support for help. I don't think they're working today, Memorial Day. You will have to wait until Tuesday.
There have not been other reports of this problem, so I have to assume that there is something unique about your computer configuration that is causing the problem.
