After resolving the blank Activation Screen issue, I hit the same problem when trying to download the state form. The Download State confirmation screen was blank. However, with the previous resolution, I used the same procedure to find the "Continue" button by wiggling the cursor around to find it about half way down and on the right hand side. I was also able to get the screen to refresh itself by changing the screen resolution. I did not think about the control+alt+del or how that might work. This was the first year in 30+ years of using TurboTax, but it just should not be that complicated.
Nevertheless, the work-a-round worked and I could download the state form and continue entering data without waiting for TT technical assistance.
