Problem Getting A Working Connection Between Board and Computer

You don't say which board you're using. As the opening post was about Nano, did you try the suggestion.

And do not hijack other peoples threads; it's considered impolite and you should have started your own one. You can report your post (see link under your post) and ask it to be moved.

And cross-posting is even worse; where do you want us to waste our time? I reply here, somebody else replies elsewhere and later on one of us wonders where their reply went.
