Hi Umberto. I appreciate your quick response. I learned when transfering all files from the my old computer, I had to re-install them outside Program Files(x86) folder. It did create its own Program Files folder, and I have all of my Flight Simulator files on a dedicated disc D instead of the normal C. All of my add-on sceneries (freeware) seem to be working fine, with the exception of payware sceneries, like yours. When I was checking your sceneries (KLAXv2) KJFK and KDFW, so far, I noticed they all went into the "Trial" mode. They were fine for a few minutes until the "Trial mode had ended" warning showed up, and then the scenery buildings completely disappeared leaving just the jetways visible. Of course, at this time I am trying to deal with sceneries, because with aircraft is also another big headache. Flight Simulator removes the aircraft and all of the gauges and sounds. For now I would like to resolve the scenery problem. Why do payware sceneries, in this case my FS Dreamteam sceneries, change or convert to "trial" mode sceneries? I have not tried the following yet: KORD v2, LSGG, PHLI, PHNL, PHTO, Zurich /Zurich terrain yet. I'm affraid the same thing may happen. Should I uninstall all of them? but, how does one install them in windows7? Obviously the old way doesn't work. Thanks for your help
