This is working perfectly and I have it all back to the way it was - I'm so happy! I've been playing pretty much non-stop, to make up for lost time. I am perfectly happy with this solution and this version (-: BIG THANKS AGAIN!
I actually reset my laptop to factory default restore and still, same problem. If anyone has a Windows 10, 64 bit laptop with a working Scrabble 3d config file, I'd be most grateful if you would send it to me. (It would be great if it was for 21 x 21 board playing 20 letters!)
