Can't access prior years 2019 and 2018?
It means they have a problem. Wait a couple of minutes and try again.
I got this message once, but the issue WAS actually on my end.
I had to reboot my computer and reboot my modem then I was back in business.
That sounds logical and I would do it but at least I'm working in 2020. At this point I don't want to take the chance of getting locked out of all three years. I will try it later in the day.
So I'm guessing ProSeries has an issue on their end and they're working on it. We've waited this long what does it hurt to wait a few more hours or even a whole day.
