me my problem is the scenery is all white on the apron and the runways.
This can only happen if you haven't installed it. Or, if the installation hasn't completed. You should have seen an error message in this case.
And I see no terminals pourtent I buy?
As explained, many times already, the scenery in Trial version is EXACTLY the same as the full version so, it if doesn't work in Trial, it will not work when purchased.
As I've said, from your description of the problem, looks like you have failed to install it properly. Try to reboot Windows, then reinstall it.
