external file button?
Opened a project that’s been sitting for a few months and am getting this on my program monitor:

All the media is linked and I can see the individual clips in the timeline, but this text is all that appears in the viewer. Where is the “External File Button”? Any ideas?
Using latest version of Premiere Pro CC2015 on a 2012 iMac with 32Gb RAM
Thanks,
