Well. we just closed three wallets on different computers and opened them all back up with no issues. You could try the add node option with 198.27.109.80 - use just one and see if that helps some. As far as we know, you are the only one having this issue. Have you tried it without your old wallet.dat file? Maybe the old one got corrupted some way.
Thank you so much for the info. Could you kindly tell me how? (Like I said - a newbie.)
Thanks again.
