Recover data from 'My LockBox'

hey I got a problem
I was using My Lockbox (as folder lock) but after a month or more, today it wasn't showing my locked folder so I removed that folder of mine from Lockbox..... but i couldn't find it in my drive it remains hidden. then I uninstalled the Lockbox but still i can't find my folder.
I tried folder options it didn't work :( I checked in program files but that lockbox not there as well :(
please guide me as soon as possible because my personal + academic all data was in that folder, I need it :(
