Thanks for lending a hand Casshern2.
I managed to get nt.pro3x's archives open, but I had to use a different, more recent, operating system to do it.
In that OS, I was able to get a utility with up-to-the-minute updates.
This is not exactly convenient or ideal.
For future reference, it would be greatly appreciated if archives are made
backwards-compatible with OS and application versions dating back to 2009 / 2010 or earlier.
In other words, compatible with "legacy" and even "deprecated" software.
More compatibility is better in my book.
