Theme plugins crashing the site.

I dont know if anyone can help me , and maybe its already been solved, i started a new site and i installed the theme, how ever wordpress tells me that the plugin blackfyretypes NEEDS to be installed, but when i activate all it does is crash the site. ANother thing is that i am using the latest version of visual composer and it seems the site hates it and wont let me edit content EX: paralax widget, contact box, etc its just blank.

I am sad because this the was kinda expensive and its makes me wana T_T
