You could try a few things to access the file:
- Use the built-in menu of the software to recover the files locked.
- Turn off hidden files because most of the folder lock applications, create a copy of the file when the lock feature is used.
- Re-install the software. Notice that it could be a risky operation because after re-installation, the software might not recognize the locked file at all.
Unfortunately, these are the only available options for this program.
