For 2017 there was no Repair Updates options. For 2017 I have run updates at least 12 times. I still cannot complete the login process. 

For 2018, I ran the Repair. However, I still cannot login. 

As for the article you linked to, I had seen that previously and tried those steps - multiple times. Everything I try checks for updates (NONE) and then takes me directly to the sign in screen. There is no option to key in my customer # and Zip Code. After keying the password, I receive the 'unable to validate' message. 

It has been SO frustrating. I was using the 2017/2018 software just fine for multiple weeks - had just used 2017, closed it,  and then one hour later I could not log into it. It has been that way for about 2 weeks now. 

I will call Intuit on Monday. Thank you. Sallie
