Is there a certain way to download them? I finally figured out how to download something a car or engine but when I downloaded a marias pass activity something went wrong. I got the route plus under it in sub folders all the rolling stock ect. I opened or expanded the folder. then closed it back and moved it over to edit and then comit. It seemed to do ok but did not show up in the sim. I then tried to move all the folders after expanding the activities folder and found that while I tried to move them all I could not seem to figure out how to do this so, I tried to move them myself. bad mistake. any help would be very much appreciated. since I got this sim msts has been on the self.
