I downloaded version 1.1 and proceeded as instructed (uninstalling previous version adn deleting any and all leftover folders and files).
After install completed I noticed in my P3d v4 SimObjects folder that I now have 4 (four) instances of the 757 (the Pw2037 and PW2040 and new a "_4D" version of the same.
Could not find any mention of these additional versions.
Starting P3d I also noticed in the Vehicle directory that only two versions are available (CS 757-200 Captain Sim House 2018 = 757-200 PW2037 and a CS 757-200 Captain Sim House 2018 2 =757 757-200 PW2040 4D) Should'nt I also have here four versions? and what is the 2028 2 about?
Furthermore, while installing additional liveries, only two choices are available - the 757-200 PW2037 and  757-200 PW2040. No mention of a "4D" or "2" version.
Am I the only one getting confused here?
Appreciate any help.
