Error of editing Textures

[Harpoon]

Im trying to edit village_t.utx but i cant.
My steps:
1) i saved the dds file included in utx
2) edit already this dds file and i saved as..... same type with the above dds (dxt1,dxt3)
3) Decrypted the retail utx file ....village_t.utx to ....village_t.clear.utx      ( i tried also the same steps with l2UTXFixer but nothing)

4) With L2Tool trying to "set" the ...village_t.clear.utx & the new dds file but cannot save it.
___________________________________________________________________________
When i tried to open the utx file in Unreal in order to delete the old dds file and import the new , i got critical error (i tried with all types of utx files - encrypted-decrypted)

___________________________________________________________________________
I tried to make a new utx file, and import all the existing dds files from the original ...village_t.utx . When i save it i saw that the size of my utx file with the retail is different.
I try to encrypt my new utx file ,and when i log in game everything in this village (..village_t) is white like this file is empty.


I checked already other posts, i did exactly what other ppl said, and i still get errors.
So now i want to import my new dds files in ...village_t.utx.
Can someone help?

Lock it, solved. I did it with l2 tool. I try the same steps with more than 7 different l2 tool and I found the correct. Thnx
