I am just starting to really get into FSX, I've played with all of the flight sims from FS 95. Now I'm retired I have more time. I was having trouble with Active Sky Next, they said I had an old version of FSUIPC and to download the new version. It asked me to register the FSUIPC or continue. I thought FSX installed FSUIPC, where would I find the code to register the new version? Also it says FSUIPC has a maximum 20 FPS rate. Is that true? I'm not all that tech savy.
