The thing is I've downloaded a texture and have the zip file window open, but I don't know where to put or what to do with the files. Can someone help me please?

You have to go here, purchase the item and upload it then.

If u want to see it by yourself, then copy the texture file to your profile in the custom folder. But if you want the public to see it ,then go buy urself a texture template.Just follow the link in the second post

UPDATE: Ive put all the things in my profile, but in free play all I see thats been changed is the floor im standing on. Help Please?
