I have bought Deluxe and Premier together. The deluxe is for my son and the premier is for my tax return.
I installed the Deluxe first on my computer and finished my son's return.
However, I can not switch to the premier version. Even if I uninstalled and reinstalled it but it still shows the deluxe version and keeps asking to pay $30 dollar for the upgrade. I can not find to input new license code that I already bought.
