I had this problem too. Running Win 7; CD version of TT Deluxe; I paid to file state; hit transmit returns and got the update required error. Tried updating and the software stated I was "up to date". Worked with help crew with no resolution. Took a swag at it and restarted my laptop. I then started TT. An update requirement popped up. I let the update run. I was then able to transmit my returns.
