Preview failing - Unable to display

[pbwall]

When I go into an already sent campaign, I can no longer preview it. I get this error:

Unable to display, no administrator or test recipient found.

I am able to still view the actual email that was sent out (test one, etc) in my email client. Anyone know what I am doing wrong?

Everything else still works like statistics, etc.

Preview needs a recipient of type admin or test to be shown (to create a preview based on his/her profile). If no such user exists, preview does not work.
