I know what you're thinking, this is an easy one... just wait....
I'm trying to open Hearthfires Multiple Adoptions in the CK so I can see how the author did something that I'm trying to figure out. When I open the mod, I get the error:
Assert
File: C:\_Skyrim\Code\TESV\TES Shared\misc\BGSLocalizedString.cpp
Line: 2871
LOCALIZATION: Error opening or reading strings file.
I click Abort:
Assert
File: C:\_Skyrim\Code\TESV\TES Shared\misc\BGSLocalizedString.cpp
Line: 2883
Failed to allocate entry array.
I click Abort:
Assert

Line: 167
Null pointer
I click Abort and the CK crashes.
Here's the fun part.
I have ALREADY edited the SkyrimEditor.ini and made sure that SResourceArchiveList2 has the DLC in it. I've also made sure to add bAllowMultipleMasterLoads=1.
I've tested this on two installations of Skyrim (I keep two installs so I use one for modding and the other for playing).
I can't find any other information on this error, everyone keeps talking about the SResourceArchiveList2 string.
Does anyone have any other suggestions?
