How do I get the Creation Kit to work with.... Dawnguard.esm .... Dragonborn.esm .... Hearthfires.esm

along with Skyrim.esm .... Update.esm .... and my own esp .... because if I double click any of the above along with the three below the kit crashes with the words

Multiple master files selected for load .... Load operation aborted .... also none of the three highres-texture packs work either .... 01, 02, 03.esp

This maybe because steam has not downloaded them correctly .... I remember seeing a download error about them sometime in the past.

This is most annoying because I would liked to have tidy up the area around my Manors which I have built with-in the game .... One of which is very exposed

a wall or fence would be nice and a door in the basemant leading to my magical teleport rooms would be superb as in all the other house's I own with-in the game

All of which have extra basemant rooms most of which has to be entered through trap doors .... With the exception of one where the children live .... well I couldn't have them climbing ladders .... Now could I .... LOL
