I need help with the add ''Static SFP1 Stock Aircraft Pack'', I had install SFPI GOLD, I played with the default campaigns and I had install some adds including this add, but the game not me run correctly... At the start the game in mod campaign, outme of the game, I don't know the happen, I do all step by step at say the instructions... I do two install for separate for test some adds including this add, but in the first install with the add, the game outme completely... And the second install happen about the same, but with a little change, I start correctly the game, but the add not apper in the game, principally at moment of play in mod campaign, the aircrafts not apper in land... The strange is, that the aircraft they apper in fly with the legend in the panel ''(...)_static'' these apper in fly but crased in few seconds, this happen at play only in misions not in campaing... Someone I can tell me why??? or what I do wrong??? P.S Sorry by me english, about I don't write
