Everytime I go to google play and try to sign in I'm told my user name or password is incorrect so I change my password, next time same message. I am the only person using my pc and no one knows my password. I see no signs of my google account being used. I have logged out and tried to log right back in and get the same message. I use the same user name and password for google play and gmail. My frustration point is high and I would appreciate any help. I've searched the web for an answer but have yet to find it. Many thanks!
