Damn, I ended up doing a factory reset to fix it all up. Wish I saw your post earlier to try that.
It was strange because a bunch of side loaded epubs disappeared after the update but a ton stayed. Then every time I restarted the eReader it was constantly trying to process new books but nothing ever happened.... should have put two-and-two together.
I found that when I could get a book open that didn't complain about DRM and it was only showing white if I did the advanced settings on the font and hit apply it would flash and show the text for a second and go back to no text again.
