Cooking Failed

Hi everyone! I'm trying to cook a little repaint from a SD40-2 using the Muff's edtior but it fails all the time.
-I have generated the Asset Registry.bin and copied it
-I have unlocked the DLL's

But still fails,
I would be grateful if someone could help me

 

Have you ever pressed Distribute afterwards? The cooking process always ends with the error message. But it is still ok. Just give it a try.

 

Thank you!

 

you've got a add-on DLC in your game DLC directory or a previous cooked DLC in your game DLC
