This is it! :)
My machine said I had that update installed under installed updates, so don't know what the deal was, but I installed it again, which means I must've removed it or something.
Anyway, just took a whole 7 minutes to check for updates and a total of 17 minutes to check, download, install and reboot!!
Thank you so much and really appreciate those direct links!! :)
Someone else mentioned already having that update. Perhaps this was a later, revised version. It did work like a charm for me, too, and so happy to have found good people on here willing to share the solution!
