Okay, I know this was discussed on some forum some time in the past, but I've searched for hours and can't find it again, so here goes:After much hesitation I downloaded 9.1 upgrade, put it in the FS9 folder, read the warning, then closed my eyes and clicked again. A message came up saying I already have 9.1 and the installation closed. Now I know I don't have 9.1, I never installed it, in the help screen it still says 9.0, and it's still missing those bridges. Why would it think I have 9.1?And here's a strange clue: After I had downloaded the update, I opened my FS9 folder and while I was pondering whether to drag the update into the FS9 folder, I noticed that the 9.1 update and the update read me were ALREADY in the FS9 folder! I have no idea how they got there, but I think it could be a clue to why the program thinks I've upgraded when I haven't.The hesitation, of course, was because of the warning about 3rd party downloads. When I went to do the re-install (that's another long story) I stupidly forgot to put in the update before adding Ultimate Terrain, Ultimate Traffic, a whole bunch of FS Genesis meshes, BEV, and a little bit more. Any comments on whether I'm making a mistake installing 9.1 at this point- assuming, of course, I can even get the #### thing to install?Thanks folks, it's great becoming part of such a helpful and passionate (or should I say addicted and obsessed?) community!Robert

Oops- one mistake- I found the update uninstall file along with the read me in the FS9 folder, not the update itself.

If you only bought FS9 recently, it comes as version 9.1.Gry

No, I bought it over a year ago, and in any case, if that were so, the Help/About screen wouldn't say 9.0, and the missing bridges would be there.

Delete the Backup folder... Then you can install v9.1 upgrade. It really isn't all that difficult to install... ;)

Thank you Bill, that did the trick, and so far no noticable problems with 3rd party add-ons.Have a great night!Robert
