I installed the theme yesterday and I was very excited about all the features it has. However, I used the demo importer in order to try some of the theme I liked the most. I began by importing "Agency" theme, but when I refreshed my website, there were no images. I happened just the same with some other themes. Then I tried importing "Band" theme. And it worked fine. This was the first theme where I could see the pictures and everything looked the same as the demo. But then I tried to import another demo and the theme wouldn't change. It just says "settings saved" (Not sure if that is the text that is show in english version, I'm writting from a native spanish speaking country). the problem is... no matter what them I choose to import. It always shows the "Band" theme. 

 I also tried choosing another theme (i mean, another theme, different from Salient, like the default wordpress themes) and by doing this, the appreance of my website did change, but it still had the "Band theme" images. 

What can I do in order to change the "band theme"? Is there any error?

I used "Wordpress Reset plugin" and uninstalled the Salient theme... This way, I could choose another theme from salient.... But the Reset plugin erase all of the content... so.. I cannot always use it.... Is there any other form?
