Mountain biking, Ain't happening.

Got a mountain bike several weeks ago and so far it is a no go. I did a quick, get the right seat height ride and did a total of 5 or 6 minutes at the local trails-flatted and that is it. My bike is very nice and includes tubeless compatible wheels so I thought I would go tubeless when I fixed my flat. Well it took a week for my Stans no tubes to get here and I have been trying on and off for over another week to do my first mountain bike tubeless install. I could not get it to work so ordered an automatic pump. That does not work. Today tried an air compressor and fail yet again. It may be tubes or no ride. There are a million online videos and they all say it is easy. I may be the only person who can call a embryonal sarcoma of the liver on frozen section but cannot set up a mountain bike with tubeless tires even one whose wheels are explicitly tubeless compatible.
