Als je even op de site kijkt van Jriver media center dan staat er :
I am suddenly receiving a notification that some files "Do not exist." I have played them before, what happened?
If you move files on your PC that have previously been imported into MEDIA CENTER, the files will become "disconnected" and MEDIA CENTER will not be able to locate them.
If this happens, you can either remove the "disconnected" files or re-import them (this will result in the loss of data, such as, category affiliations, play counts, per track equalization, and other non-tag stored information) or you can "reconnect" them by specifying the new filename/path in the "File Name" property in "Media File Properties." View a file's Media File properties by right-clicking on a file and choosing "Properties."
If you choose to remove and re-import, you can quickly remove all "disconnected" files by selecting File> Library> Update Library...

Dus als je files hebt geimporteerd in media center en daar na hebt verplaatst krijg je de ze melding.
