Problem for my account....

hi,

  there is serious problem with my account.from yesterday i was not able to access my account....for login
  it was giving my id and password is incorrect.i tried lot but didnt got any solution.then i sent mail to c-sharpcorner n got reply that - "  Hi Pravin,
  Sorry, we found no records with this email address .Please confirm your email address again."
 then i created new account and start accessing,its fine now but problem is i lost my all post of previous account.
  i checked forum questions where i commented by old account.....now that comments showing with some another users name
see this post for e.g:- http://www.c-sharpcorner.com/Forums/Thread/133566/retrieve-file-from-database.aspx
  check second comment ....it was given by me but its showing by the name of "Mahadesh" now......!!
  Thank you,
  Pravin.
