Unable to log in to my YouTube to upload or approve comments

Not sure what happened exactly, but I am unable to log in to my own YouTube account in order to upload new videos or manage my subscribers' comments. At the same time there is no problem logging in to Google, GooglePlus or Blogger. Hmmmmm. Thank you for being patient as I am looking into solutions.
