I can see what happens with those that do not read the cautionary note for the link to Flightsim.com telling them to be logged in FIRST.
I can click on the link to the rwy12_1.zip and it takes me to the flightsim home page. I am
not logged into the site I click on File Library in the menu bar at the top of the page then pick Search Files option and the search page pops up. Type in rwy12_1.zip in the File Name box and the correct file pops up. (nothing else) I click on 'Download' and
NOW is when it tells me to log in first. I can see why it could frustrate newbies to that site to get that far only to have to stop and join the site if they are not members etc. Nothing else to say but my old mantra of RTFM!
Anyhow the link is working fine and the filename to search for is correct. If the user is logged in to Flightsim.com FIRST then things works correctly.
