1Password trouble

Hi all. This is a cross platform question. I'm considering a new Mac, an am getting ready to trade this one in. When I tried to look at 1password, here is the problem, or problems. first, long ago, I bought 1password outright, so I don't subscribe to it. second, I do have a Master password. I do not have a password account, so I can't get the setup code, or secret key. Third, I vaguely remember jusing it with dropbox ages back but again, I don't have access to that, or the old email I was using at the time. can anyone make sense of any of this I'd be interested to hear your thoughts. thanks for any help.
