Checking in to say that I am also experiencing this same issue and the same error message. If there is a fix, I'd love to know.
EDIT: I tried to hunt down the error log; the document I found was 31 pages, but I have copied in below the part that appeared relevant to the problem. I can paste more in if more info would be helpful (I don't really know what I'm doing):
