Hey Buddy, I was in the same situation, I had to get a new PC laptop, and had to re-install my FSX Deluxe Edition in my new laptop, I had to go and add drivers and all to my windows 10 laptop, it took a while; after the software in stalled into the computer, I was flying again, I was afraid that I have forgot everything, especially the landing, but I done pretty good in landing; what I do hate about it I have to start over with my flight time, I had, over 500 hours and the awards that I received on my old computer. I love flying on my computer, jumping into different airplanes and just taking off. I love the Flight Simulator X and cant wait until the new one comes out. So, keep on flying and get back into it like I did. Oh, for awhile I flew on my iPad, but to me it wasn't the same as flying on the computer its more challenging.
happy flying and God's speed
your fellow Sim Pilot
