اینم جواب نامه ای که به سازنده اش زده بودم:
Dear sir:
If the folder was protect on Normal Security Level, you can reset your password with Restore Center.(In the main window, Click SETTINGS>Options>RESTORE CENTER>select a protected folder to restore)
However, because of the irreversible algorithms, you(even us) won't be able to unprotect without the correct password if you protected that folder on Hign or Highest Level.
ps: Restore Center is only available to regisered users.
Please let me know if there is anything I can do for you.
