"couldn't sign in"
Droid RAZR HD
I opened google calendar and received the following popup:
"Couldn't sign in" - "You typed an incorrect password or your account has changed. Re-type your password. If you forgot your password and need to recover your account click here."
I was able to get away from this devil by going to my main menu. I opened G-mail with no problem, but could not click on anything in my email that wouldn't bring back that damn popup.
Re: "couldn't sign in"
Stupid question: did you change your password? try signing out in the settings and signing back in
