Help with GMAX Skyraider please?

I am having trouble getting the GMAX A-1H skyraider to work on this site. I have tried files ("updated") from FS2002 Vintage page 1 at the bottom, and older version on CFS2 Aircraft pages 19 and 23. They are all the same filename "GZRA1Hv1.zip". I follow the directions on the readme file. Went to a seperate website to get the weapons. Loaded into stated folders. Nothing shows up on the aircraft list in Free Flight. Didn't check other menu options. But I loaded the SAAF Spitfire from here just fine. Although, that ran off an install file. The skyraider is just a plain .zip file
