How can i recover files from audio manager?(hideit pro app)

[AC Question]

All my pics and videos that I had hidden on this app are vanished all of a sudden without me even personally going and deleteing them. I Cannot find any backup where I can restore them. Please provide me solution as all of the files were really important. I tried googling n they have only provided one solution( go to es explorer- select option 'show hidden files'- program data- language- .fr- and open videos, pictures folder there you will be able to find) but its still empty after trying this solution too. Please help
