Some time ago i uploaded to lfsw my skin for XRG XRG_greddy_d

but i can't use it in game,

when i join track with this skin game "says" "Your car's skin was not found at www.lfsworld.net"

try re-upload it to server, and delete older one.

If still not working, make sure it correct in all forms.

If still not working, I have no idea.

I've done this before. did not work

The only thing I can think of is that the file in your LFS folder must have a sightly different name to the one on LFSW...

You could try re-uploading it with a different name to see if you get the same result?
