I logged into an account on my youtube app (the one that comes with the phone) about a week ago. i think i downloaded an app just a couple days ago, but now when i try to open my marketplace, it says "Google sign-in You entered the wrong password or your account has changed. Please re-enter your password. Username *********@youtube.com Password *blank*" when i try to enter the password for it, it closes, then re-opens this same message. ive logged out of my youtube and used the one that is registered to my phone, and ive even gone and erased the youtube account. i cant access my market at all and i need to update an app. please help.
