problem with changing theme to jsn decor pro

I just installed Easy Blog on my joomla-site (built on JSN Decor Pro) and I
want to use in Easy Blog as default template the jsn_decor_pro.

I followed the instructions given in the documentation from JSN Decor Pro,
but Easy Blog doesn't show the JSN Decor Pro theme, so that I can make it my standard theme.

What I did:
I copied the folder "jsn_decor_pro" from the the 'template'-file and
copied it to "components/com_easyblog/themes"
via dreamweaver.
On the server I see "components/com_easyblog/themes/jsn_decor_pro"
but when I go to the themes of EasyBlog it is not visible, so I can't make it my standard.

What else do I need to do - or what is my mistake?
