Unfortunately this issue with the nVidia geForce acceleration card software has been more complex to solve than expected. We've attempted 3 different fixes and have had to iterate on each because of remaining issues.
Unfortunately the problems were entangled throughout our missing font detection code on document open.
We are currently testing the engaged fixes and things are looking more stable now so I beleive we should have an available update by tomorrow (Friday 9/4).
I'll post the link here as soon as it's handed off to me.
