If you can see your Bitshare 1.0 account name in Bitshares 2.0 then you have successfully recovered your wallet (I don't know is it possible), make new password and create backup of your wallet FIRST. Then skip first part and use second part of this guide. If not try this route.
First Part
Download bitshares wallet 0.93c install and synchronize it and try to recover wallet from your brain key.
If successful make new password and export your wallet, details about migration here:
