Unable to uninstall Folderlock – “error 0x801F0004”

I can’t seem to get rid of folder lock and the locked file it created. I recently installed folder lock and I used the program to secure one of my files, which made a file with .flk extension. Eventually I wanted to remove the program and tried uninstalling it through my control panel but I get an “error 0x801F0004”. Has anyone else thought of a way of getting through this? Thanks!
