I am trying to find the missing files for this rocket series here : http://www.reddit.com/r/KerbalSpaceProgram/comments/1rjynt/****_germanys_space_program_recreated_using_real/ I already installed all the parts that he listed, but apparently there must be something else missing. Is there anyone on here that successfully loaded the Aggregat rockets? Apparently the KzInterstageAdapter2 seems to be missing, although it should have been included in the Procedural Fairings mod... Thanks!
