Hi Jessica, 

Welcome to Box Community and glad to assist! 

In order to get it to work, can you follow these troubleshooting steps and try again? 

• Updating your browser to the latest version
• Clearing your browser's cache
• Using Box with an alternate browser, computer, or network. 
• Temporarily disabling any internet security/firewall programs to test whether they conflict with Box (Note: you may need clearance or assistance from your organization’s IT department/helpdesk to do this)
• Temporarily disabling any plugins/extensions in your browser
• Removing unwanted extensions, plug-ins, ads, pop-ups & malware:
  
  • Chrome, Edge, Firefox, Safari

Hope it helps!
