I am having the same issue with kjfk. Purchased real color for kjfk and my planes are still looking like a drab gray. I also have real color add on for tower 2011. I uninstalled tower 2011 completely and reinstalled tower 2011, real color and real color kjfk then rest of add ons. Started kjfk up and no change on plane colors. Does it make a difference that I bought kjfk from just flight and real color kjfk from feelthere. Both files are in tower 2011 folder.
