I click on the "Download File" button and save the file on my desktop and extract the files...what do I do from here so I can start using the program?
What program are you referring to my friend?
I'm guessing that you want to install new aircraft into your sim. Here is a tutorial, if you have any further questions feel free to ask.
Any of the programs are my issue. Lets take FS2002 Aircraft Grumman F-14B Tomcat VF-103 Jolly Rogers for example. I'm running Microsoft Flight Simulator 2004 as my main program.
I have that aircraft in my folder, just follow the link that I posted above.
