I have been trying and trying, over the last few weeks, to follow all the instructions and get my prior years of ProSeries Basic updated.

I'm stuck. 

I've updated 2020, 21, and 22.

Cannot get 2016-2019 to work.

Should I reinstall those years from scratch?

Can I ignore them and work without them as long as I don't have to go back and amend anything?

Thank you!
