Trouble with buildings showing up

[nightmare51 3]

Could anyone please help me I have four lots that I have downloaded quite a while ago.  The problem is I get posting saying that a building is now showing up.  I made all the buildings in Gmax.  If anyone could please check it out for me and give me an idea on how to make the buildings show up, I would appreciate it.  The best example is the prison that I built.  I was told that the chow hall is not showing up when they download it.  Another is the weigh station building now showing up.  Thanks in advance.  there all under nightmare51.

Do they just show up as brown boxes?

If you made the buildings then you need to include the models in the uploads.

BarbyW thank you but I don't fully understand. Do I just upload the building itself? Because I uploaded the lot with the buildings on them. Can you clarify this to me please. Thank you.
