I've started having this problem after the beta patch, can't open the Creation Kit now.
It shows me this message (my game is in Spanish):
"MASTERFILE: LOCALIZATION: Lookup failded for ID: 0x00012584 from strings file: STRINGS/skyrim_ENGLISH.DLSTRINGS"
clicking 'yes to all' leads to...
"Assert
File:C:\_Skyrim\Code\TESV\Tes Shared\misc\BGSLocalizedString.cpp
Line:2872
Failed to allocate entry array"
then
**crash**
I have the three Dlc's and looked in my AppData for the correct load order and I think it is.
Skyrim.esm
Update.esm
Dawnguard.esm
HearthFires.esm
Dragonborn.esm
I don't have the duplicate "skyrim" word in the plugins doc and I had my country localization line added as well.
I tried adding the dlc bsa's in the resource line and that don't fixes the prob. Still crashing.
