I have the same problem when trying to restart turbotax 2025 after activating and using it 3 days earlier. I have the umid file but adding UseCustomUMID=1 on a new line at the end of the .ini file did not help. Calling the customer support was useless as all they could say was it shouldn't happen so just use up a second activation to use the program again. I don't want to use up all my activations because I do wish to install it on my laptop etc. And who's to say this wont just happen again? I just had the same problem with turbotax 2024 not recognizing a previous activation on the laptop I was using last year. This is not good Turbotax. What now?
