How can I edit skill effects/textures without them being corrupted?

[Vokt]

I first export them using UE Viewer and after I edit them I import them to UnrealEditor(L2Editor) to the package the texture/mesh belonged to. When I try to open l2.exe with the edited files I get an error that the files are corrupted, any guess to what am I doing wrong?

After editing with EnrealEditor, the file must be re-encrypted.

Damn, I thought because the UE could read the files encrypted there wasn't a need to decrypt them back, thanks.
