Hi,
When you download the theme and plugin it is downloaded as zip files, so you need to extract using zip extractor for it, you might be getting files but it not be visible as zipping. So you need zip extractor for it.
If you got stuck somewhere then send us the query. If you want we can set up your theme, make a user for us assign administrator role and send us the username and password along with the Site URL at support@vwthemes.com.
Thanks
