Hello everyone, I have a problema when a I try to load skyrim.esm + update.esm, the creation kit shows some messages as It says the tutorial and then at 90% show this

"Assert

File C:\_Skyrim\Code\TESV\TES Shared\misc\BGSLOCALIZEDSTRING.cpp

Line: 1556
LOCALIZATION: Error opening or reading strings file."

And options Abort, Retry, Ignore

Then the creation kit show 2 more messages and then crashes

What can I do?

Thanks and sorry for bad english
