It is the display resolution. Change the display resolution to 1280x960 or keep trying different resolution until it works for you.
The software won't install properly either if the resolution is not set correctly.
It is terrible that not all the turob tax representatives on the phone understand this problem. When I had trouble installing the software, the first person told me that it is the firewall issue. When I had troubling paying with credit card for the state filling fee, the lady on the phone told me the problem is their internal credit network issue.
