Quote from racer autov8 :

How can you have XRT while you're demo licensed?
Maybe you happened to use a crack/keygen?

LFS is not even mine.
Heck i don't even have the DEMO Version.
Whether its licensed or not i don't know.

I know how to skin because i even did some skinning for war thunder.
Just open the main folder, skin and there you go.

Should i be worry about this matter?
