Imported images won't show

[#1]

I frequently make graphics in Illustrator, then import them into Premiere Pro with no trouble at all. Starting yesterday, the imported files aren't showing properly. In Source Monitor, they're just black screens. In Program Monitor, nothing shows up. Is there a glitch in the updated version of PP?
