All is not lost buddy.
You are not alone in your setup woes.
Once you are up and running, the learning curve is not steep at all.
What OS are you running?
I’m going to have a guess, Windows 10 since you mentioned trying to follow the guide…
if so, try this guide by @anon2520759
(I haven’t tried it myself, but it looks like a great write up)
Read to the bottom before starting and look for any updates / redirects eg.
If you get stuck along the way just ask.
or if you are using another OS, that would explain the issues you had, so let us know and myself or someone else will direct you to another guide…
goodluck
