theme styles

hello,
Nice plugin. I have some trouble. In the results after submitting, the styles of theme are losted and appear my downloads in very different way. To give you more, instead of archive download page with their purchasing buttons for each download, with 3 downloads per row, appears only the feautured image with the content from the editor, 1 “post” per row. So it seems that do not load the archive download.php or any other edd php file. What I could do? Do I hve to make new php for the results of search? or how to use the existed?
