ZOHO MAIL -- All of the sudden I can't download and open PDFs

When you receive an email in Zoho Mail with an attachment, the attachment has 2 links in it:

1. Download
2. View

I can't Download JPGs or PDFs anymore.  This just started yesterday.  Nothing happens.  

The View link works fine, but the Download link doesn't work!


HELP!!!
