Hello,
I'm afraid I'm not from Sheffield and I'm not a walker but I've been using TL since 2007 and I've just reinstalled Windows 10 on my PC and was looking for the TL website and found this thread instead. Real shame about TL (it was the best in class in 2007) but with v3.18.02 being released in 2013 I guess the writing was on the wall.
I would really appreciate getting my hands on the v3.18.02 installer - i've got lots of .trl files I'd still love to use.
