How the ♥♥♥♥ i find this files

[CrusaderKing]

So, I'm still having problems with this game, but this time I was able to find the meaning of these errors in the Buffout 4 dictionary. Anyway, he pointed out two crashes one of MCM, which is pretty much rearranging the load order and a DLL Crash... And that's where the problem comes in. The crashlog pointed out these files:

# LIST OF DETECTED (NAMED) RECORDS #
- Name: "Textures\Interface\DLCBannerDLC01.dds" | 2
- char*) "Textures\Interface\DLCBannerDLC01.dds" | 2
- void* -> tier0_s64.dll+000C045) | 1
- void* -> tier0_s64.dll+000C17E) | 1
- void* -> tier0_s64.dll+005BFE0) | 1

How do I find these files?
