After 10 years of Flight Simming, I had per chance to stop at Madrid- LEMD the other day. Most of the aircraft were parked on the dirt/grass. I spent parts of 3 days trying to use AVSIM files to correct it. No luck, so I got mad, shelled out $30.00 and bought the Simwings version from SimMarket. Still had aircraft on the ramps parked on the grass/dirt. Tried 2 more days trying to fix it with AVSIM files brought up under, "Madrid" / Scenery Fs2004. One guy had 6 pages of delete, copy, change,etc. Must have done something wrong because this time the COMPLETE, whole airport was on grass/ dirt. No cement anywhere? Has Simwings made an up date to their Madrid, after the real airport was updated a couple of years ago? It's still a mess for me on FS2004 and I'll bet my last two dollars that that's the reason that Aerosoft has NOT, repeat, NOT included it in their Airport Enhancement Services (AES) Series. Has anyone been able to fix this problem? If so, HOW?The ONLY redeeming factor in all of this mess is that BEFORE making all of these changes to my Fs2004 I used a new program, "ACRONIS TRUE IMAGE HOME II". Not only is it a great BACK-UP program, it has a feature called, "TRY and DECIDE" that you can start and all changes to your computer will be made in a "vertial state". Then you try the changes that you made and if you like them, they will be made permanant, or if you DON'T like the changes, check a box and ALL of the changes that you made will dissappear like you never made them !!!! If you do must sceney adding/changing etc, this program is worth it's "weight" in gold. I think www.acronis.com is their address and it costs about $50. It's really a 1st class back-up program with TOO many feathures to list here. jerrycwo4
