You need KT's fixes to be set up as an override, which means the computer needs to read the files first before it reads the files they affect. In my "Mods" folder, I have a "Packages" folder and an "Override" folder. My "Packages" folder has several sub-folders ("Hair," "Clothing," "Hacks," etc.). Putting my cc into subfolders like that serves two purposes: it makes it much easier to locate individual .packages, and subfolders are automatically lower in the file-reading hierarchy. Anyway, set up your overrides correctly, double-check your resource.cfg file to make sure it's set to read all folders and subfolders in the "Mods" folder, and everything should work correctly.
ETA: The computer would probably read your "Overrides" folder before your "Packages" folder anyway, because of the Magic of Alphabetical Order, but I tend to compartmentalize a lot.
I tried everything, even making an overrides folder and putting the files in there, and still the same problem. I did get something to work though, I put the store fix files in my packages folder and put the ccmerged file in dcbackup, and everything seems to work ok, except one thing seems to be invisible on the blackjack table and my sim won't gain any gambling skill from it.
