Q: How can I de-authorize all of my computers if I do not have access to ANY of the computers I am authorized on?

I am trying to authorize my current computer, however I have authorized the maximum amount of computers. In order to deauthorize all of my computers (to authorize my current computer) I need to be able to access a computer I am currently authorized on but I do not have access to any computers that I have previously been authorized on. I need to be able to deauthorize my computers without having a computer that I am authorized on.
