Can't activate Turbotax Home and Business
Turbotax won't let me activate. As in, there is no menu or dialog box for me to enter my activation code.

I purchased and downloaded initially through Amazon and had the blank screen process. Contacted TT through twitter and was told 3rd party downloads are janky and I should get a refund. Did that and then purchased the DVD and downloaded from installturbotax.com and have the same blank screen problem.
I've gone through all the troubleshooting processes I can find related to this issue with no success. What is going on?!?
