I can't sign on to deauthorize all computers
I have a laptop that I know has been authorized before but, for some reason, it's not recognizing it. It says that I can't authorize this system because I have reached my limit. I do not have the other machines that would have been authorized before. I would like to try to "deauthorize all" but I can't get authorized and sign in in the first place. I really don't want to lose all of my stuff but I need some help. Thanks.
