I have 2 laptops and two desktop computers. I have installed TurboTax on all four, but when I update the program on the two I use the least, it asks for my license code again. Since this has happened more than once, it is now saying I am at the limit of 5. How can I get the two that are now no longer working to recognize that the computers are already recognized. I have returns on these two, that I can now no longer access.
