Team project

As Nate mentions, you must have the media on YOUR local system.

And you've found the Team Projects Media Management dialog, which is good! Like me, I think a lot of users don't know about that at first. So for others reading this, the other MUST ... is again as Nate mentions ... you MUST link to that media from the Edit/Team Projects/Media Management dialog and NEVER link to media from the Project panel or Media Browser panel in Premiere!

I'm including images of the path in the menus to the Team Projects Media Management dialog option, and then that dialog open showing the options. Normally, you'll map to your local drive with the top option.

The only person who uses the Project panel or Media Browser to add media is the Owner of the project.

Hi there.  

Do you have a copy of the media somewhere in your possession?  If that is the case, you can link the media within the media management dialog using new media mapping for the offline items by selecting the offline directory at the top of the dialog, clicking the new media mapping dialog, then navigating to the correct location on your own system.  This is outlined in the following link.  Do not use Make Offline... or Link Media... for this operation as it will change the location of the media for the other users of this team project.

Hope this helps.
