Free hide folder issue

Hello,

I used free hide folder for hiding my brother marriage video files. But due to some reason my harddisk crashed and i lost those files. But due to one recovery tool R-studio i was able to restore those hidden but there is an issue i am not able to play those files and i have forgotten password to unlock those file. Those files show full size when i see its properties it shows complete size of file. Please help me how i can recover those files i have that hard disk but i have done my window again and upgraded to windows 8. Now dont have either the password and neither the original operating system on which i used free hide folder to hide files.
Please help me those files are really important for me as my parents have died and those videos were the last time i took there video. Please help me and thanks in advance. Images attached regarding files please do have a look.
