I have uninstalled and reinstalled several times. I downloaded the software from both Amazon and the Intuit site and installed/reinstalled both copies.
Still having the same problem. It will not authenticate.
Also interesting, a week before downloading TT Premier, I had downloaded and installed TT Business with no issues. I ran TT Business and filed a business return with no problem.
When I uninstalled TT Premier, it also uninstalled TT Business - I don't know why.
