I wondered if a programme might be causing trouble and decided to try System Restore to get back to an earlier time. SR., however, will not work. I keep getting the message :
failed while copying registry from restore point Error 0x80070570
I can access other sites but not the one I desperately need.
Any advice you can offer will be gratefully received and I offer my THANKS in advance.
If I have posted in an incorrect section, I apologise. I did try to search for the coreect one.
