And today everything works fine. Followed same instructions I wrote down previously.
Only thing I did differently was delete everything relating to osmc from my desktop downloads folder as I had multiple copies of the osmc loader app and I may have kept using old downloaded loaders instead of the 4th and 5th iterations that I had downloaded in recent days. Everything clean worked fine.
Now I just need to buy wifi extender so I can run it in my bedroom.
Call it closed.
