Microsoft has notified us that there is an authentication Failed error when you go to install the latest tax update. These are server issues on their end and in light of the current situation, they are unsure how long this will take to fix.
There is a workaround, just manually install the TX.cab file yourself. Log into CustomerSource and download here.
If you are not familiar with the manual steps, here is Microsoft documentation, or feel free to contact our support staff for assistance.
