CS6 on Mac OS 10.8.3
I've seen a few questions posted with the same error message but none that I have found really had the same problem as I do. I can't get Premiere to import any media. Two of my files came up offline. I went to link the media and it gave me the error message I described in the title. I then tried to import the file seperately rather than linking the media and still had the same problem. My next tesst was to just import a random video file to see if I could import anything at all and I still came up with the same issue.
Edit: I just imported an audio clip successfully. Not sure if that narrows anything down or not.
Edit 2: Now I can import video, just not the ones that come up offline. The offline clips were working fine the last time I worked on this project and they play back fine in quicktime.
