Losing images in Outlook 2011

I'm a new mac user with Outlook 2011 installed.  I depend on it for business.  All of a sudden I can't see my attachments.  jpegs, pdfs, etc.   You can see theres' a paperclip attachment from the sender, but when opening the email, or clicking on the attachment, there's nothing there.  This happened overnight.  Everything worked great over the past 3 days.  I feel like I'm losing my mind.  I also get vendor emails with rich html images.  Upon opening those emails, the bar shows up that says:  To protect your privacy some pictures in this message were not downloaded.  When I click the button to download the images nothing happens.  I also have a picture (jpeg) on my signature that went away.  Am I destined to these issues with this program?  Any help with fellow outlook users would very much be appreciated!
