None of those KUID's listed on that sticky seem to be downloadable with TS12 CM.
All the digholes, floors, sides and walls you need are available for TS12. I know as I made them...

Edit:
Some of the KUIDs I just posted are also listed in the very first post, post 3, 50 and 51 of that sticky I pointed you at. So I suggest you check if your CM actually works or let your eyes checked out as I expect there to be something wrong with at least one of the two.
