Get your taxes done using TurboTax

I have only downloaded my software on 4 devices.  How do I fix this issue?  Also, I updated my windows on one of the laptops and it is asking for the activation code again and now indicates I have already maxed out on the number of devices I can download the software, but I already had this on this particular device.  This new license code had cause many issues this year.  What is the fix?
