Retrieve "Folder Lock" folders from another PC

Hello,

My computer just died and I retrieved the hard drive. I had some folders locked with Folder Lock software. I installed Folder Lock in my new PC (which has its own hard drive), used the same Master password than in my old PC, and connected my old HD as an external drive, but how can I retrieve the locked folders from that old hard drive? Are my folders from my old HD unreachable?
