How i can find a hidden theme?

Hello,

First: excuse my language errors – english is not my better. I use Google translator and i know: he is not perfect.

Please, take a little bit of pacience and try to understand my problem. Thank you.

In my personal and free account, on pt-br.wordexpress.org (at Brasil) i use the theme: Ocean Mist – by Ed Merrit.

I would like to use the same theme in my professional account at American WordPress. But he does not appear in my options (not appear in my research with the author’s name or the name of the theme – it is as if he did not exist).

I want this theme not just for esthetic reasons (although they are also important). There are several technical reasons for this choice – among them, the translation for my language.

Of course I can find another theme with the same solutions but I would like to use the Ocean Mist.

Can anyone tell me how to do it?

Relevant Information: I dont use FTP – my host offer one direct link to WordPress and i work directly inside of WordPress Control Panel
