Looking for Twysted-pair.com's electronics lessons

I am looking to buy Twysted-pair.com's full set of "learn electronics" lessons
If any one knows how I can contact the Mrs. of the brilliant man who made the lessons or has the lessons, please let me know

I have the complete set, but they only run on 16 bit pcs, maybe 32, but definitely not 64

I got my hands on the lessons and they were not working in windows 10.

I installed windows XP 32bit in virtualbox and its works fine.
So, you can still use the lessons in windows xp 32bit if you want.
