Okay so I'm somewhat new to tails. I got persistance, and decided I'd change all my passwords on the markets I have an account on. I changed them to random words, and saved it into KeyPass. Well, being somwhat new to tails, I saved the database into the wrong destination. When I closed tails, and go back on now, it didn't save. And wow, guess what? I forgot those random words. What do I do? I have orders on two sites. Some markets will let me reset my password if I had my public key on my profile, but I don't. Am I completely fucked? I remember my username and pin. But that's about it.
Happens to everybody at least once. Contact the market using another username and give them as much information about your account (things you would know that other people wouln't) and see if they will reset it for you. Explain to them what happen in the same way you explained to us here now. They might wait a day or two incase they consider your attempt a hijack - but dump everything you can think of about the account - when you signed up, what orders you made, etc. and help prove to them you are the account owner.
After you lose your passwords once, you learn to create TrueCrypt containers and backup everywhere.
I agree with the other comment about not needing Tails - just running Whonix or Tor with TrueCrypt container should suffice if you're just making the odd order.
