Shopperpress Not Installing

So, I picked up the theme for shopperpress and I’m having issues installing it and so far nobody on the “support” has been able to help me. I install the theme as I would any other wordpress theme through the wordpress dashboard. When the theme is finished uploading I go to activate it and it turns my entire website blank. I can’t even get to the wp-admin page. I’ve gone in to the files through my hosting and deleted the them then reinstalled it multiple times and it always does the same thing.

Does this thing actually work or is it a waste of money?
