Walkthrough does not work, presents a blank screen

TurboTax just does not work. I got halfway through my return and then it stopped walking me through. I cleared cache, cookies, history in browser and did a cold reboot of my PC -- and still nothing. I started a new return, and as soon as I click "Walk me through everything" I get this blank screen and in the lower-left corner it says "no form." On the old return, I can get to a form by clicking the Forms button but it is never the right form.  Here is what I get:
No forms show upNo forms show up
