Help! "Pin it" plugin has locked my site – won't even pull up my web URl anymore

Any help would be really appreciated! I installed the “Pin It” for Pinterest plugin by Canha. Now, when I type in my blog address, https://www.laurenfairphotographyblog.com, it won’t even load the page. I already contacted Godaddy, the host, and they said from their end the site is live, so I know it is on wordpress’s end. I can’t log in to even delete the plugin. I found the page in this forum on “how to delete plugins if you can’t access admin,” and I don’t understand any of the instructions. I am a photographer, not a web developer and don’t understand code. If anyone could help, I would really appreciate it!
