Many thanks for all of your replies, I have downloaded that particular files as suggested and have stored it for (unhopefully) future use. To get round the complete problem of this mess, I have installed a new hdd in the system and done a complete fresh install of Windows 7 and of course all of my FSX and all of those other lovely programs that I previously had. However to get my scenery library back to it's original state is going to take about another two weeks or so, to find and download all of that scenery that I use to have, around 125Gb worth, and nearly all freeware. Then of course to sit back and watch Plan-G rebuild it's database and update the waypoints, is going to be so much fun.
