  2. uninstall PostgreSQL (from within Windows) if necessary
  3. rename the VPOP3\pgsql folder to something else
  4. install PostgreSQL (preferably into the VPOP3\pgsql folder, but that's not critical)
  5. restore the backup you did earlier (http://wiki.pscs.co.uk/how_to;restore_a_database_backup)
