Computer wizz I am not. I have a Lenovo laptop. Microsoft Edge. It might happen every 3 or 4 weeks. I come to this site, and it wants me to register or sign in. When I try to sign in it tells me to enter my e/mail address and they'll send me a special code to sign in. When I sign in with that code, I'm good for a few more weeks. Maybe I'm remembering my sign in name wrong or my password code wrong. Hope this makes sense. Any other time I click on the site it comes up OK. and away I go.
