Getting google chrome sync problem need help

What I’m trying to do is sync Google Chrome on my home and office computers. However, I am having a major issue with editing my "pass phrase." I click on the “Chrome customize and control” icon to view the Sync error message that reads "update sync pass phrase" (I don’t have a pass phrase, but I do have a password!!). When I click on that message, it takes me to a window where I have to input my non-existent pass phrase. The message says "You already have data that is encrypted using a different version of your Google account password. Please enter it below." I do NOT have a different version of my Google account password. I try entering the password and nothing happens. If I go to the Google Dashboard, it says "your account seems to be empty (I emptied it last night by clicking Stop and Clear in the dashboard). To start using sync, log in to your chrome browser." Well, I can't sign in because I keep getting the error message above. Furthermore, I’m already signed in because I can see my email address at the top right corner of the screen. So, I'm basically in a continuous loop that takes me nowhere. I have wasted too many hours on this, and I'm about to give up on Google Chrome. Please tell me how to change my pass phrase (I don't even have a pass phrase!!).
