You already have an account on the Hive @mauriciozoch ! Actually you just have to log into it and then you can get going .. It will show everything you ever did on steem until the last Saturday. Since that day they are separate .. Unfortunately I do not use esteem, and never did use it in my life .. I always used "steempeak", and now on hive its their corresponding frontend "peakd" .. You can try to log into hive via the regular frontend from the "hive.blog" site, or maybe the "peakd" site and try if you can get in from there .. I am sorry, cant help you with esteem.
