In order to decrypt your files, open Mywinlocker and go to File Decryption. All your encrypted files should be available there. If you can't find any of your files there, it's possible that you won't be able to recover them anymore. Even if on your virtual driver (Yo-Safe) you have occupied a small amount of space, this is reserved for program's files and probably your files were deleted when you uninstalled the application.
