Can't Launch

[Umbra Domini]

You are on the latest drivers now, right?

Despite all the evidence leaning toward the driver update breaking everything last time (as mentioned in my post), I took a leap of faith and updated my driver to the latest version, on my now-factory restored computer, and now it works.

I'm really very sorry to have wasted your time. I was convinced the driver was just bogus, but now it turns out it's fine (so far).

Thank you for your help.
