I've been getting this error when I start Chrome on my MacBook Pro for a couple months now:
Your profile can not be used because it is from a newer version of Google Chrome.
Some features may be unavailable. Please specify a different profile directory or use a newer version of Chrome.
Note: I have confirmed that my version of Chrome is up to date.
Once I press 'ok,' it's fine and I can use my account as normal. The only thing that has changed is the little icons on my bookmarks bar are blank.
So finally today I decided to address the error and came to find that I needed to resync my Google account. I didn't realize why, but after entering my current password it asked for my old password, so I guessed a bunch of old ones and voilà! Everything changed back to the account I had in 2012. I lost all my bookmarks and themes.
Is there anyway to resync to my new account?
