Okay, so I fixed the error myself by installing QuickTime.
Now I get the message that in the future QuickTime is not going to be supported anymore and I should transcode the file into a non-legacy format...
This clip also imports for me in Premiere Pro 12.0. When you get Properties for the clip, it should report Type: MPEG Movie (just below File Path).
This sounds like something could be possibly wrong with your MPEG importer or license. If Ann's suggestion of the Cloud Cleaner Tool does not resolve your issue, then I would suggest that you contact Customer Care. Contact Customer Care
