undelete tools

Hi list, It happen to me that I un-intentionally delete one document. I don't have the backup. I try undelete from http://muzaffar.home.cern.ch/muzaffar/undelete/ to recover the file but it seems not working (actually the installation is failed). Could anybody here give me a clue how to recover the deleted file. Any suggestion is very much appreciated. TIA Edwin This is virus free email scanned by mail.nsi.co.id
