Need some help please! I have been trying to figure out this "Building preview"? I have had this problem so many times now and looking for help on 3 year old questions isn't to useful to say the least.
It is extra annoying because I'm doing this for a friend and he paid me to do it so I don't want to be like "Naw man this glitch/problem is going on and I can't figure it out"
Please ask me if you need extra info and please get back when you can.
