And my pg_xlog can not copy to D:/3SDATABACKUP/PITR/WAL from 06/01/2011. How to fix error ? Please help me

Here is my Archive
# - Archiving -

archive_mode = on        # allows archiving to be done
                # (change requires restart)
archive_command = 'copy %p D:/3SDATABACKUP/PITR/WAL/%f'        # command to use to archive a logfile segment

Thanks in advance
