Problems with the Optic from planets!!

[Ares78]

Hello, Iam new here, and my english is not so good.
I have celestia vers. 1.3.2
I??d like to have a better look for my earth, moon etc.
I found some maps who looked good, but when I install it, they dont work.
I heard anything about a level5 File or something.
Wich file must I download to see my earth in a other Optic?
My problem is the english language.
Please answer me in a simple english, otherwise I dont understand it.

1000 thanks

greetings

Ares

What is your language? Perhaps somebody here can speak it and make it much simpler to help you.
