I am frustrated and furious as you are.
I have found a workaround that worked but, again, I am so angry with the poor testing done by Intuit.
The workaround (suggested by another user on here) is crazy: when you get the license code field and you can't type into it, just type the code (without ashes) even if apparently you don't see anything happening, and click return. It takes the code.
In a few words, you have to blindly type the license code.
