THANK YOU! This worked. I tried everything that everyone else posted in this thread, but nothing worked.
I must have had my external drive plugged into my usb port when I installed TT. I could not get past the activation error. I plugged my external drive back into my computer and clicked on TT program and it came right up with no errors this time. I appreciate you posting this resolution. You saved my hours on the phone with TT and now I can file my taxes.
